Summary
Factorio 2.0.72 (stable) crashes after extended gameplay with an access violation inside the belt transport system (TransportLine::deactivate). The crash occurs during normal gameplay (not on load), after many autosaves, and appears related to belt updates running on worker threads.
This may be a race condition involving belt entities, possibly triggered or exacerbated by mods that interact with entity updates.
stuff
What Was Happening When It CrashedSingle-player game
Hosting locally (no remote players)
Factory running for multiple hours
Large belt network
Large Bot network (>14000 bots)
Regular autosaves occurring
Crash occurred mid-game, not during load/save
No immediate on-screen error; game abruptly crashed to desktop.
Crash Details
Exception Code: c0000005 (Access Violation – Read)
Crashed Thread: Worker thread
Map tick at crash: 73812473
Stack Trace (Key Portion)
TransportLine::deactivate
TransportLine::update
TransportLineManager::update
WorkerThread::loop
This strongly suggests the crash originates in belt transport line lifecycle handling, possibly due to invalidated data being accessed during a multithreaded update.
Frequency
Has occurred more than four times so far
Save provided to reproduce
Has not been tested yet with mods disabled (will update if needed)
Reproduction Steps (Current Best Guess)
Load the provided save
Let the factory run normally
Allow bots / belts to operate for an extended time
Crash eventually occurs during belt updates
If I can narrow this down further via mod isolation, I will update this report.
