The typical crash comes from a mistake in side editing or modifying the LUA, but for this map I haven't done anything like that to provoke a crash. It crashes when I click spawn, by the way. Here's the BFront2.txt:
EDIT: it had something to do with my lighting, I removed it and it works fine now.

I'm using the objects from Naboo, so that makes sense. I copied the odf and msh folders over but there was no effects folder for the "fountain_halo" or nab_sfx_fountain". Where would those be?

I tried removing the calling of those effects from the odf for the nab1_prop_fountain and it sitll crashed, but this time upon loading.

My new BFront2.txt:

For your missing effects, look in:

BF2_ModTools\assets\worlds\NAB\effects

There is no BF2_ModTools\assets\worlds\NAB\effects. I did search as well, psyc0fred...weird. I went ahead and just removed the fountains from the map and it still crashes (but this time on spawn again). Here's another BFront2.txt:
I'm at a loss...

You obviously deleted them at some point, i'm looking at them right now.

Could you possibly send them to me? I don't think that is the problem now, though. (see BFront2.txt)
