[GAMEPLAY] Taric Ultimate-Icon Is Said "Avaible" While It's Not.

I used Taric's ultimate few moments before I died, so I pressed the "R" button and ** I'm getting killed** before the end of the 2,5s delay. But when I respawned the **"R" **button was **clear, saying I can use the ultimate **even If I **press it multiple times nothing happen's. ** I think somehow the cooldown is started, but the icon is remained the same.

I play the game in a realy low-performance PC, so I had no chance to record the play, but in case I saved the logs.
