alright,, ive created another level (its currently finished),, if i open it in JCS (1.23), say "Save and Run", it goes just fine,, but, if i open a new server with this level, or when i do it in splitscreen co-op, as soon as the player(s) stop flashing, it crashes,,

i really dont know what the probem is/could be - whether i could have too much in a certain layer, whether i have too many destructo-thingies, whether i have something else im not supposed to have,,?
