um so yeah a relog sorted this but I thought I would make the bug report anyway because it was just weird. Was in a dungeon (normal Black Rook Hold) and noticed my GCD and cast times were really slow. when I opened my character panel it had a lot less mastery and crit than it should’ve, and haste wasn’t even on there.
anyway, a relog sorted it and the stats are all back how they should be but something buggy happened.
