Activatable Items Bug
Basically, with any activatable item that I have on any champion, when the item comes off cooldown, instead of becoming usable the item just sits there for about 10s before it can actually be used. This has happened to me every game I've played from 24th Jan - now across ranked, normals, and ARAM games
I set up a custom game to take some screenshots to illustrate the point:
^ in this screenshot, my warding trinket has just come off cooldown, but as you can see, it has not gained a charge that I can use, instead the icon just sits blank for about 10s before gaining a charge
^ in this screenshot, Frostqueens has just come off cooldown and I'm spamming 2, but nothing is happening. Again, it takes about 10s before the item is actually usable.
This first happened to me in a ranked game and really threw me off. I've been hesitant to play ranked while this bug is affecting me... I've tried restarting my client, my computer, playing multiple different champions, running different masteries... nothing seems to prevent the bug... I'm tempted to put in a support ticket, but I thought I should post this here first.
