Just played first game with the new rune as Anivia and couldn't get past 50 stacks. Game was ~35min and had 14kp so no it wasn't just that I couldn't land a spell..Tried leading with a different spell each time too and nothing worked. Ez on my team said his was working fine so not sure what caused it. The icon never showed up to say it was off cooldown either like it did at the start of the game.
Keep an eye out in your games
I also had the same issue in a game playing as Anivia, mine stopped at 150 stacks and would no longer proc or give me bonus mana regen
Had this too. Got to 150, then used the ult and could no longer stack.
Pretty sure it's due to her ult being toggable, it might break something
i got the same issue with sion, could not stack after i died first time, proabably something with respawn champs like anivia and sion with the interaction that their passive form is a "different" champ thus rune wont activate since the first champ its on never reapear
Apparently it's a bug where if it's on cooldown and you champion enters some kind of "undead" state (anivia egg, sion, karthus, guardian angel, etc), it no longer stacks
The bug still exists today. It seems a rather major bug when you can basically lose one rune for it.
