(BUG) Aurelion Sol

A visual issue:Aurelion Sol ults then he dies after appling the damage.The ult doesn't show on cooldown but you can't activate it for it's real cooldown.Is like the ability is ready but you can't use it . It is very weird.

I can't test it out because i don't have a PBE account but last game i playd Sol cause he was free and this happened.
