For the last month or so, I've been getting moments were the game will either grey out and freeze for only a few seconds, or will lock up so badly that I have to restart my client (this mostly happens after boss fights in dungeons). All of them give me a descriptions of the crash being an AppHangB1.

I have no idea what this means, but it's starting to get in the way of my ability to play, and it's really pissing me off, to be completely honest.

If anyone has any idea what these mean, or how to fix it, I will be so happy and make you digital cookies of your choosing.
