[Rseding91]

The problem is the game doesn't support trains overlapping and because of the collision mask change they don't collide and thus overlap.

[Rseding91]

I've added an error message at startup when rolling stocks have invalid collision masks so it won't crash the game after the next version of 0.15.

[evildogbot100]

It doesn't crash when the overlapping rolling stocks are on different rail and different rail_category. Can you please not remove this possibility?
