Aery bug

I just played a game with Zilean and at some point i just didn't have Aery anymore, which isn't really convenient when i build Athenes + Ardent Censer. Thankfully it didn't cost me the game but that would be nice to get it fixed asap, because i love this mastery opening up more utility to Zil. I just can't stay when the bug proc'd but i can link my match history here : https://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/3423802888/38202756?tab=overview
