Warwick Q and W bug

Warwick Q and W will not activate after ULT. Q and W will not cast for at least the normal cooldown time after the ULT is completed, regardless of whether the Q and W were available or not. It really is a crippling but and has been originally reported in this thread http://forums.na.leagueoflegends.com/board/showthread.php?p=49270524#49270524

Any ETA on a fix would be greatly appreciated!!
