Nexus Blitz bug

Discovered a bug just playing against a Pyke. When we completed an event (loot the Teemo I think it was) we were granted Guardian Angel. Right after we got the buff I was Pyke ulted as Renekton and the GA did not work. Pyke ult went through GA and killed me then my model got up as if I was revived, gave me the revive hp but I just sat there. Not sure if this is the same for other champs just lettin you guys know. Hope to see a fix
