Oh, gee, thanks for getting that song stuck in my head.
Haha, anyway, new version 3.36 with savegame after initial cutscene and a few civilian vehicles added for decoration.
Unfortunately, as I was playing through to design this, I did, in fact, get a crash, very similar to the ones I was having earlier throughout OFP. Frankly I've got nothing but speculation now. I was playing in 1280 X 1024 resolution, and maybe that's what did it in even with this new card.
I don't think that it is a global variable since the screen just freezes. It may be something like many scripts running at once depending on how you play the mission and that could be induced by the mod as well as your mission build.
I wouldn't think it's many scripts running at once. There should be at most 2 scripts looping simultaneously, 3 if you count one with an @ command. I've even eliminated that @ in the latest version.
One looping script is in beastcomms.sqs and checks whether they're all dead, and the other is in recon.sqs and looks for enemy reinforcements.
There are other scripts but they should take only a few seconds to run through. It doesn't sound like something a modern computer couldn't handle. Then again, this is OFP we're talking about.
