Wanted to put in my issue too.

As of today's patch on July 29th i'm having random crashes ive never once seen before. It first started when i tried to zone into ST and immediately crashed with the same error in this forum post. I tried to log back in but after i clicked my name and the load screen started to pop into the game it would then crash again. It did that repeatedly. I deleted the files and pulled from my backup of the game just in case and i then logged in. However i think this was simply because what ever was crashing me was gone because it put me back into mor dhona. So i thought "yay" and was talking to my fc while standing there and then i again randomly crashed. Ive since updated my drivers to the latest just to check...and all was well till it randomly hit again.

So in short I have no idea whats wrong but its literally stopping me from playing. Ill plop the standard info below but i cant see anything wrong on my end.

Windows 8.1 Pro (updated)
Nvidia geforce gtx 660ti
Intel I7-4770K
8 Gig Ram

and although this is similar to all the other posts....here is the event log
