Don't know if it will help - but you get somtimes bug with single weapon fire if both weapons are in different modes /dual mp5 will not work if one is set to single and other to auto fire/.
There is problem with ag/dx switch. I have started new game after p1.1, and my Rangers had high Dx low Ag after p1.2 install. I used the fix-tool written for the previous patch and looks like it is allright now.
