Dromed crashing

[Marshall Banana]

Dromed is crashing every time I go into game mode. I press alt+g and the screen goes black, and then a "send error report" prompt comes up.

What have you done to the current mission between the last time it didn't crash and the first time it did crash?

[Marshall Banana]

I had roombrushed, and put textures in the proper places in the texture hierarchy, messed with the ambient lighting, and I had added some new terrain

You might try area brushes to isolate different sections to see if it is a specific location that's causing the problem.
