[2.1.7] Crash involving train wait conditions

[boomshroom]

After updating my save, a few minutes later the game suddenly crashed. I was eventually able to save mere moments before the crash to make it easier to replicate, and confirmed that it happens with and without mods enabled. The exact enum value reported in the crash log seems to change each run though.

Thanks for the report. Do you have this save file from before it was migrated? I suspect one of the trains on screen was recently upgraded and the logic to preserve the train stop during upgrade was messed with by a mod. I'd like to reproduce the full issue from the original save if possible.

Actually, I was wrong. I see the issue now and it's fixed for the next release.
