Another issue that I've been having since the patch release is that I'll be walking around in a zone, and suddenly my screen will go completely black. After a few seconds, the zone will reload and everything will be back to normal.
I'm wondering if that's what the game is trying to do when we crash to desk, but it fails for some reason.
In any event, it's occurring a couple times per day with long play sessions. No rhyme nor reason when or where it occurs.
