I've started playing heavy mod game few days ago (krastorio 2 + transport drones + mining drones + construction drones + few QoL mods).
Happened all of the sudden as auto-save was starting (auto-save didn't finish as I lost all progress). Restarted, and it happened again few minutes later. Restart again, and happened again couple more times. It seems to have happened when I built new supply depot connected to mining depot. If I don't build that supply dept, it does not crash.
Factorio crashed. Generating symbolized stacktrace, please wait ...
