Battle CTD when switching weapons, every ranged unit

[alreadyded]

I had this massive bug creep its way into my mod, I am not quite sure when it started. All my units used to work fine not too long ago, but now all the ranged units (even ones I never edited in any way) cause a CTD when they switch to melee. I can not think of anything that could cause ALL of them to do it. The modelsdb and edu entries are the same as they always were, and that doesn't explain the massive scale of this anyway. The animations could not cause this either but I checked them anyway and they are good. The log shows nothing, just says system.rpt error.

Only thing I can think of that could cause every ranged unit to do this is the BAI (I am using G5's RBAI) or a corrupted file, but I can't imagine either causing this either. Has anyone ever heard of, or experienced this bug before?

I fixed it, must have been a corrupted file. I reinstalled M2TW and that solved it.
