Large districts with over 200 beavers experienced pathfinding stutters where beavers would get stuck on stairs or triple floodgates. Build 17278206 rewrites the agent goal-priority system.
This is the most critical warning for Build 17278206. Because this build updates the game’s core code, most mods will break.
The most notorious issue before Build 17278206 was the "water desync" problem, where water would visually behave differently from its actual mechanical effect. Build 17278206 completely refactors the shallow water algorithm.

Timberborn Build 17278206 represents a critical milestone in the post-apocalyptic beaver city-builder, serving as a bridge between the groundbreaking Update 7 and the definitive Timberborn 1.0 release that debuted in March 2026. This build is a culmination of the "Transit-Oriented Beavers" era, solidifying the game's shift toward complex 3D logistics and automation. The Evolution of Beaver Transit: Update 7 and Beyond
Build 17278206 sits within the lifecycle of Update 7, which revolutionized movement with faction-specific transport systems:
Folktails’ Ziplines: These enable high-speed, two-way travel across vast distances, allowing colonies to bypass difficult terrain.
Iron Teeth’s Tubeways: A modular, underwater-compatible transit system that excels in the tight, vertical industrial corridors favored by the Iron Teeth.
3D Terrain and Tunnels: For the first time, beavers can dig tunnels and build terrain blocks atop existing structures, enabling hanging gardens and skyward farms. Key Features and Stability Enhancements
While the major version numbers grab headlines, builds like 17278206 focus on the "grease" that keeps the gears turning. Key areas of focus include: 1. Automation and Logic
This build period refined the Automation toolset introduced for 1.0. Players can now deploy advanced sensors to manage their colonies:
Logical Operations: Using buildings like the Relay, players can set conditions (AND, OR, XOR) for power and water management.
Sensors: Flow, Depth, and Contamination sensors allow for hands-free dam and sluice management, preventing floods or badwater contamination.
HTTP Integration: The introduction of HTTP Levers and Adapters allows real-world API interactions, a favorite for modders and advanced users. 2. Visual and Performance Fidelity
Performance was a major hurdle in earlier experimental phases. Build 17278206 incorporates optimizations that: Timberborn Build 17278206
Reduce Lag Spikes: Improved CPU/GPU utilization for settlements with hundreds of beavers.
Atmospheric Upgrades: Enhanced skyboxes (featuring stars and clouds) and water transparency across Medium to Ultra presets.
Wet Fur Tech: Visual feedback where beaver fur appears visibly wet after swimming. Faction Differences in Build 17278206
The build maintains the strict mechanical identity between the two playable factions:
Folktails: Focused on renewable energy, vertical farming, and now, expansive zipline networks.
Iron Teeth: Focused on heavy industry, engines, and modular tubeways that can traverse badwater. Survival in the New Era
With the inclusion of Unconventional Maps like Pressure and Oasis, Build 17278206 challenges players to use new map objects like Water Seeps and Geothermal Fields. These maps force a departure from standard river-damming strategies toward more localized, aquifer-based survival.

This report details the status and content of Timberborn Build 17278206, as of April 2026. Build Status & Availability
Build 17278206 is currently the stable version of the main branch, having recently graduated from experimental testing in mid-April 2026. It represents a significant stability and balancing update following the major structural changes introduced in earlier versions like Update 6. Key Features & Changes
This build focuses on refining colony management, water physics, and accessibility:
Beaver Well-being & Achievements: Reaching maximum well-being is now easier due to a calculation shift. The game now uses a true average rounded to the nearest whole number rather than flooring the value. Water Management Enhancements:
Wave Dampening: Dams and Floodgates now include wave dampening, significantly reducing "sloshing" and erratic water levels in reservoirs.
Fill Valve Algorithm: The logic for Fill Valves has been replaced with a more efficient algorithm that reaches target water levels more precisely. Performance & System Updates: Let me know so I can give you exactly what you need
Structure Memory: The game now remembers all built structures globally rather than only checking those currently on the visible map, which aids in accurate achievement tracking (e.g., Master Builder).
DirectX 12 Removal: To prevent unsolicited crashes on incompatible hardware, official support for DirectX 12 has been removed.
Steam Deck Optimizations: The game now initializes with an increased UI scale by default on Steam Deck to improve legibility on the handheld screen. Critical Bug Fixes
Water Pump Exploit: The long-standing exploit that allowed for unnatural water pumping has been patched "for good" in this version.
Immersion Fixes: "Extra" Folktail kits will no longer spontaneously spawn when loading a game with sleeping beavers.
UI Clarity: Fixed blurred status icons for Gates and corrected building particle effects that occasionally displaced HUD icons. Developer Context
Following this build, the developers at Mechanistry have shifted focus back to experimental branches for future content, including further tweaks to 3D water physics and automated sluices.
I notice you mentioned "Timberborn Build 17278206" — paper.
If you're asking about Timberborn (the beaver colony-building game by Mechanistry), build 17278206 appears to be a specific Steam build ID, likely corresponding to Update 4 (experimental branch) or a subsequent hotfix from mid-2024.
However, your mention of "paper" is unclear. Could you clarify what you mean? For example:
Let me know so I can give you exactly what you need. If you just need the official changelog for that build, I can help summarize it.
As of April 2026, Build 17278206 for Timberborn refers to the most recent major update to the Main Branch (officially released on April 20, 2026). This build consolidates several experimental features aimed at refining water management and enhancing game stability. Key Features and Changes in Build 17278206
The primary focus of this build was the official integration of improved water physics and automation tools that were previously in testing. Refined Water Dynamics:
Fill Valve Algorithm: The logic for Fill Valves has been completely replaced with a more efficient algorithm designed to reach and maintain desired water levels more accurately. a forum post
Wave Dampening: To address the "sloshing" issue often seen in complex water systems, wave dampening has been added to Dams and Floodgates. Automation & Sensors:
Flow Sensors: Players can now use flow sensors to measure water rates. These can be configured with thresholds to automatically toggle other water-related buildings on or off. Major Fixes:
Water Pump Exploit Reversion: Developers specifically addressed a previous attempt to fix water pump exploits that had inadvertently broken gameplay on shallow river maps like "Helix".
Performance & Stability: Fixed several critical crashes, including those occurring when exiting the game directly or clicking on Rubble. Formal "Paper" Structure
If you are drafting a report or "proper paper" on this build for a community log or personal archive, you should structure it as follows:
Title: Technical Review of Timberborn Build 17278206 (Main Branch Release)
Abstract: A summary of the transition from Experimental to Main branch, focusing on the stabilization of 3D water physics and automation.
Hydro-Engineering Analysis: Detailed section on the new Fill Valve algorithms and the impact of wave dampening on large-scale reservoirs.

Conclusion: Final assessment of how this build resolves long-standing "water sloshing" bugs and enhances late-game automation.
Steam :: Timberborn :: Update 6 - now on the experimental branch!
Timberborn is a city-building game where you manage a colony of beavers in a post-apocalyptic world. The number 17278206 refers to a specific Build ID on Steam, which corresponds to a specific version of the game (likely an update released in late 2024 or a specific experimental branch).
Here is a summary of what that content entails and how to handle it:
Badwater sources were introduced in a previous update, but they were notoriously difficult to block or divert. Build 17278206 introduces a subtle but crucial change: Badwater sources now have a visible hitbox when placing levees and explosives.
