[kovarex] [0.17.54] Crash when saving a single train loop with one signal

Post by AngledLuffa » Thu Jul 04, 2019 10:43 pm

Playing marathon deathworld, I (finally!) started building a train for uranium. I built a loop with a single signal, planning to go build the other side next, and the game crashed when trying to save it.

Attached is the log file and a save game from just before the crash. If you place a signal immediately after the station, then try to save, the game RIPs.

Windows 10, version 17.54, no mods

Weirdly, if you place the signal before the stop, or if you place signals on both sides of the stop, the crash doesn't happen. The crash only happens when the signal is immediately after the stop and there are no other signals on the loop.

Thanks for the report, it is fixed for the next release.

These kind of corner cases are the reason I applied the consistency check on save, to figure them all out.
