Bug with cursor states

Since the last 2 patchs, when I press on a spell and then on a second one then release the first pressed spell my cursor becomes blocked into the spell's state (meaning the game thinks I still have to select a target), this is game breaking as I can't click on the mini-map or even use some spells until I re-use the first spell. It can happen on ults. example: I'm with {{champion:13}} , I press on R and then on Q; then I release R and then Q and there we go I'm blocked into the Q state until I re use R.
