[2.1.7] Crash driving train: Unknown enum value: 123

I'm not sure what caused this. I was driving a train, entered the map screen, and my game crashed.

This looks important (from the log):
8820.443 Error WaitCondition.cpp:423: Unknown enum value: 123

"Unknown enum value" in this context indicates that an internal Variable field of type "enumeration" was somehow set to an unexpected value. This often indicates Memory Corruption has occurred.

0.009 System info: [CPU: AMD Ryzen 5 2600 Six-Core Processor, 12 cores, RAM: 32011 MB]

It looks like you are using a system with non-ECC memory, which is susceptible to external interference (cosmic rays, microwaves, static discharge, nearby lightning strikes, etc). If it happens repeatedly you should consider running a memory test to check for physical issues with your system.

Good Luck!

Similar crash similar situation, memory test shows clean, might be a linux bug looking over the crash logs, on arch using gcc 16.1.1, but getting 79 instead of 123.
Edit: Consistant crash when a temp stop expires with nothing else in the schedule
