I am wondering what is going on w/ the infected instance because me and another group member have had our game crash 3 times in this one run from the moment we hit the ground portion. It seems to happen every time a new message window pops up from either a BOFF or from an enemy. I've run this instance more times than I can count and this NEVER happened to me before. This is however the first time I run it since season 2, so I'm assuming it's something brought on by the new patch. I haven't been in any other STF yet since season 2 hit live so I am not sure if this will happen in any other 1 but as I said I never had this problem prior to season 2.
Here's my dxdiag report
