I recently had to reinstall WoW, and totally forgot to backup my interface folder...
/facepalm
I got most of my addons i remembered back, but there's one in particular.
I can't remember the name, obviously, but what it was was an Error Handler. I think it was the Lua Errors specifically. Like, instead of the giant field obscuring window, it popped up and icon on the minimap with the number of errors. Anyone know what or where to find it?
