Umm, FYI, when using latest compiled nightly (not sure which one that is, but the one used on 4/27/2012 ~7 PM EST), when you hit the escape button during a mission, the quit query takes a while to come up, and when it does, the game doesn't know where everything is -- it snaps back and forth between two positions.
e.g., I had an enemy fighter targetted, and it shows a speed of 348+ in both positions, and I am at a speed of about 180 (can't tell cause the quit window is in the way; however, that's about what it was when I hit "no" to check) -- the distance to the enemy fighter fluctuated between 622+ in one frame and 625+ in the next, back and forth.
Also, exiting took longer than normal.
Not sure if this is cause for concern, or if it's even related to this mod (perhaps this belongs in SCP board?) Anyways, I'm going to try clearing my cache, who knows, maybe that's it.
