Rust Known Issues, Workarounds and Fixes

Livestock reacts slowly when server NPC processing is over budget

In the LIVESTOCK update, Facepunch explains that NPC work is distributed across frames within a time budget. When over budget, NPCs can respond more slowly. That explanation concerns server-side NPC processing and should not be presented as proof that every individual player’s frame rate or connection is faulty. [1]

A Windows 11 client crash continues after local checks

For crash investigations, Facepunch may request the .dmp file corresponding to the failure. Its Windows 11 guidance names the per-user Rust crash directory. A dump is diagnostic evidence for support; collecting it is not a claim that the crash has been fixed. [2]

Documented steps

1. For the Windows 11 path described by Facepunch, look under C:\Users\USERNAME\AppData\Local\Temp\Facepunch Studios LTD\Rust\crashes. Sort by Date Modified and send the matching recent .dmp file privately to support with what you were doing when the crash occurred. [2]

Steam not open? Rust fails at startup

Facepunch’s startup guide orders its suggestions by how commonly they resolve the reported problem. Start with closing the Rust client and Steam, then reopen Steam before Rust. The message alone is not evidence of a server ban or a damaged character save. [3]

Documented steps

1. Close Rust and Steam. Re-launch Steam, then re-launch Rust. [3]
2. If the message persists, close Rust and check for Steam client updates from the Steam menu. Apply any prompted update and restart Steam before testing Rust again. [3]
3. If a Steam beta is active, Facepunch’s next diagnostic step is opting out of Steam beta participation, applying any required update and restarting Steam. [3]

Unknown file version: verify the Rust installation

Facepunch says file verification is commonly used for Unknown file version errors. This uses the Steam installation repair check. It is a separate operation from reinstalling the game or replacing a world save, so start with the documented integrity check for the affected client. [4]

Documented steps

1. Close Rust, open its Steam Properties and select Verify Integrity of Game Files. Let Steam finish; Facepunch notes that verification may take several minutes. [4]
