Map crashes, during gameplay or loadings

[66492f0460879xdiesp]

The attached map crashes frequently when you load it (changing levels) or when you load savegames (within it). If you can check the crash log and see what's causing this, please help.

The map is an adapted SS1 map, uses diffused lightning only, has lots of elevators, and custom music\sounds not included here (the map crashes fine even without them). I checked the log myself and there's a number of warnings, but I'm not sure whether they're relevant (the other maps I have that don't crash, are similar).

Edit I've also included the map where the bulkhead button is (1_hydro1), in case the problem is actually there. To replicate this crash, I quicksave and trigger the bulkhead. Then I quickload and repeat: very soon, it will crash. The bulkhead in this case, is a corpse to hack in the first cultivation cell after the 2 robots area.
