My costum story keeps crashing after some time?

[Romulator]

Funny. First playthrough, crashed.
Second playthrough, crashed.
Third time.. nothing.. 4 minutes in, have run past two grunts.. I genuinely have no idea what the problem is o.0

Edit:
The only thing I can find out of the ordinary is that you're missing this in your custom_story_settings.cfg:

Code: (Select All)

MapsFolder = "maps/"

Everything else seems fine though. I did delete a few things which were outside the map (I think there was a wall, a billboard and a ladder top), perhaps try removing them too (billboard and ladder top are off to the right of the starting room, and the wall is underneath the map to the left).
