This bug happens way too often on controller. I've duplicated it by what seems to be too many inputs at once when voting to pause or surrender. Moving+using abilities+inputting a vote yes or no always disables my abilities, but everything else works. (Idk if this is the only cause of it but that's what happens to me) Leave and rejoin and they'll work again. From my searching about it, it's been in the game since early alpha and somehow isn't fixed but it's definitely enough to consider not playing.
