Not sure if this has been brought up yet. I just kinda scanned over the thread titles. But ever since 1.2.3 I have been getting short lag spikes in dungeons. It took me a while to isolate the issue, but it's only happening in dungeons, and it's primarily happening during and shortly after looting. Also I'm not sure if it's tied together, but once entering a dungeon, I no longer get screen announcements like achievements and exploration notices. A /reloadui does seem to reset the notifications.
