Darius auto attack bug (Dunkmaster skin?)

I played Darius in a ranked game and i found out that when i used Darius's combo i could not auto attack or use Darius's w ( i believe this is because Darius's w is auto attack related). I tried Darius out in a normal game to test if it was just a one time thing but I got the same problem again I could not auto attack any champion and or minion after using a combo. I tried Darius out in one more game to test out this bug again and further discovered because I had another Darius in my game on the enemy team that the bug may only be on Darius's Dunkmaster skin i also tried to resolve this bug by disconnecting and reconnecting it did work but after i used another combo after i reconnected I got the same problem again I also discovered that dying in the game would allow you to auto attack again but after a few more combos I got the same problem I could not auto attack again or use w. The problem comes and goes sometimes i do not need to die nor disconnect and reconnect to the game to get rid of the bug but sometimes it does not. I believe this bug may only be on Darius's Dunkmaster skin from talking to the other Darius who was in my game he said he had not encountered this bug while playing Darius with no skin but he said that he has seen multiple people with the Darius Dunkmaster skin encounter this problem. Please help or please look into.
