[0.12.16] Rotating a locomotive crashes the game

Post by FraGag »

Rotating a lone locomotive on a running train that has crashed into some other rolling stock causes the game to crash.

To reproduce, start a new game with the attached custom scenario (locomotive-crash-demo.tar.gz, unpack in the scenarios subdirectory), let the locomotive crash into the cargo wagon, then put the mouse cursor on the locomotive and use the Rotate key to rotate the locomotive.

When a locomotive on a running train is actually moving (there is no obstacle in front of the locomotive), using the Rotate key on the locomotive does nothing. However, if the locomotive is colliding with some other rolling stock, it is possible to rotate it. The locomotive moves forward a little, then the game crashes.

As a side note, it's also possible to rotate a moving locomotive when it's being driven manually. It looks a bit weird to me, but I don't know if it's a bug or if it's intentional.

Thanks for the report, fixed for the next release. Rotating locomotives while driving in manual is intentional.
