What, no one can help? Has this kind of problem even occured before? Don't tell me I've got a problem that no one's ever seen before??
I'll list some other things I've done, and maybe it'll help narrow down the list of what might be wrong. I tried clearing the cache on my xbox, reloaded the morrowind data by running the game, and then put only 1 plugin (no-glo) in the data folder, and it still froze. I made sure to follow that guide to remove dependencies on plugins too. I also tried loading the same plugin as both an ESM and ESP, and even tried using the original file (the plugin straight from being unzipped, before I tried removing dependencies.) None of it seemed to work.
Can anyone think of ANY reason why this might be happening?? Seriously, I'll take ANY idea, just throw them out. If there's no conventional reason why this is happening, maybe someone's crazy, unconventional reason will get lucky.
