I was playing ARAM today when something suprised me, 
ulted our nexus turrets a few seconds before our inhibitor respawned and the effected lasted until a little after the inhibitor respawned. Usually, the nexus turrets would have been invulnerable with the inhibitor up and running, but they were still vulnerable. So was our nexus while the inhibitor was still being destroyed.
Next level Bard play.
If you see other bard did this... Please report him.
Thats really funny. Well not for you but hey rito coding.
an no one abusing this has been banned why?
Quite the bug there
This has been a bug for a few months actually. I remember seeing a video on youtube about it. Surprised its taken this long to pop up on the boards.
EDIT: https://www.youtube.com/watch?v=76iHi7lVWtQ . So this has been known about since May of last year...
Any state change that occurs while something is invulnerable doesn't pass.
IE: you can walk into the enemy spawn if you queue a movement order, zhonya as your team destroys nexus, then after it wears off you walk in, even though when the nexus dies normally all commands are canceled.
So I'd imagine its the same here.
This bug has been around for a quite few patches now, at the minimum. If something is supposed to become invulnerable, by either a nexus being destroyed and a Bard ult/Zhonyas or an Inhib respawing, as your video shows, they won't gain the invulnerability, leading to them being vulnerable (No really, right?). Vandrill did a video on this a while ago.
