Boss kill error

[afroshouji]

Hello. This error pops up anytime I defeat a dungeon/raid boss. I've cleared my settings and even reinstalled the addon, and it still comes up. It started to happen with the last big patch. I see that it mentions Edit Mode a lot, but I haven't touched that at all since the beginning of TWW. Thank you.
