I'm having this strange problem with Sins, and having looked around a bit I didn't see anyone else with a similar problem...

I'm making a mod, and up until yesterday it was going fine. I put in two new abilities and a fourth race which is, right now, a kitbash of vasari/TEC and three re-scripted vasari frigates. I played with the english.str file a bit, got everything the way I wanted, tested, and went to sleep. Next morning I woke up and went back to messing with stuff, and after I had started the game (I'm using the developer exe, if it makes a difference) it froze around the point where it makes the first autosave. The game works fine without the mod on, but even if I remove the new abilities, and even the new frigs, it still freezes. I'm not getting a minidump error or anything, the game is simply freezing.

The only thing I can tell so far is that according to the Task Manager, Sins usually sticks at around 825,000kb of memory used, but when it freezes like this it goes up to 1,600,000 for a bit and then drops to 1,100,000 and stays there until I kill it off. Another thing I noticed is that on the core Sins is using, it goes from 50% utilization to around 93-96%. The log files are always empty when this happens too...

Anyone have any ideas as to whats going on?
