Okay, so I've run across an occasional bug.
Sometimes, on my priest, if I do a /reloadui ... range checking breaks. It starts seeing everyone out of range, and if I go into the menu to check what the range is set to, my normal range (of 40 yards) doesn't show up at all. Changing it to the other settings (30, and I think 15 was in there) doesn't seem to give me any love.
A second reloadui fixes it, but my raid starts getting irritable when they have to wait on me *twice*.
I'm assuming it's just a race condition of some sort, but I don't know for sure.
Anyhow, just thought I'd mention. Keep up your good work!
I have seen the same issue when you startup (after getting booted from the server) and come back in while the raid is in combat. All of the windows will show OOR till you do a reload ui. Not sure if it's related but similar.
