Exception_Access_Violation when trying to run SOME of my custom story maps. [Solved]

[Your Computer]

Well some of them are the DLC (Justine) monsters, and some entities/static objects I had to edit.

Like I had to edit a wall to make it a entity, things like that.

I would suggest making a back up of the map and start removing the custom entities/objects that you made/edited one by one until the map works again. If you removed them all and it still crashes the game, then i'm not sure what to tell you.
