I did relog, yes. It might have to do with the Character cards (Mercedes' reduces skill cooldown) causing trouble, but I don't know.
EDIT: Maybe it happened because I logged off with the skill on cooldown (I crashed before the patch and I didn't log back on again) and before I went on my Mercedes I set up the character cards first (one of which reduces cooldown time). Maybe the skill ended up with a negative cooldown somehow?
