HUGE Quinn and Tahm Kench Bug

I was playing a normal game and I was playing Quinn with Tahm Support. Tahm ate me as I used my ult and i was valor. As i reactivated my ult tahm ate me at the short switch between valor trading with quinn and i was stuck playing as valor for the rest of the game. My q w and e all preformed like they should when playing as valor but my passive still marked targets while my e did not. When i attacked the marked target it would use the quinn autoattack animation to detonate the mark. I played the remainder of the game as valor no matter if i executed or died to another champion. My ult was on a permanant 1:59 sec cooldown and my ult description read "spell not found:" I believe i kept the attack speed and i did not keep the movement speed buff. This absolutely ruined my game, sure it was funny at first then it was incredibly frustration. Please fix thanks [(http://i.imgur.com/9U2Vfcn.png)]
