Katarina's Q and R stopped working for a bit
just experienced this minor bug for a bit on summoners rift. i pulled my combo on varus and janna and then after that I found out i couldn't cast my q or ult, despite it being off cooldown.
When I died i could use the abilities again and for the rest of game but i dunno just weird.
EDIT: As Kagaiou suggested, the bug happened after 30min, and we destroyed mid inhib at the time, I'm not entirely sure but I think I levelled up during my combo
