I was messing in editor with your mod, placed unloader nearby rails to get size assesment, but never did anything else with it and just deleted them with right click while in /editor mode. On picture, inside red zone is where they were placed. Now, if i take a new bp of the green zone, game crashes. If i copy post that somewhere and try to create bp, game still crashes (that's how i noticed it).
