Off Topic: You might not be the most famous person for funny POTD's on battlefrontfiles, but from what I've seen you've certainly sent in the most. On Topic: One solution to this is to copy the BF2_modtools thing in the folder and place it in your Gamedata folder in your Star Wars Battlefront II folder. run the application and play...err crash (it crashes, right?) your map. A text document will appear called BFront2. It will have a list of all the errors in your map. The ones that say Message Severity: 3 are the ones that make your map crash. After this is all completed, post it up.
Oh yeah. I forgot all about that :P It's called Bfront2.log. Open it in Notepad and post it here.
