Tested in a 10-man so far (25 this weekend); no more taint.
Excellent. I still don't know the cause and just fixed the symptom. It will do for now.
Still hoping for an option to remove the minimap button, like all other mods that have such buttons have. Will be deleting Minimap.lua and hoping it doesn't bug out when doing so soon.
Yes that is coming. Remove the minimap line from the raidbuffstatus.toc and restart wow. Should work but I've not tested it.
