Bubbles' Take Cover Bug

[[DARE]jayU]

Description: I was playing as Chronos in a match and a Bubbles was on the other team. The times I am about to provide are the actual game times.

At 41:18 game time, Bubbles' Take Cover skill works as intended, as it does every occurrence before this time. Here, you can see him manually cast Take Cover.
At 41:45 game time, Chronos jumps near Bubbles, whacks Bubbles three times, and then throws up his ult. Bubbles uses Take Cover just before the moment Chronos ults. Bubbles is just outside of the ult and not affected by it (even though it appears Bubbles should have been stuck on the outside of the ult). Suddenly, Chronos can no longer attack Bubbles, even though Take Cover is not showing.
At 44:50 game time, Chronos jumps near Bubbles and hits him five times. Suddenly, the same thing happens so Chronos waits until he can attack Bubbles to finish him off.

I asked my teammates if they saw what I saw, and they all agreed that Bubbles must have used Take Cover, but it was not showing whatsoever. Upon examining the replay as Bubbles, you can see that in both instances described above, Bubbles does in fact manually cast Take Cover but nobody but himself can tell he is in his shell.

I'm going to confirm this as a graphics bug, since he is take covering, the model just isn't changing/animation isn't playing.

It does appear to be a graphics bug, but the bug seems to originate at the time of the Chronos ult at about 41:45 game time. After Take Cover ends, why is Bubbles able to auto-attack Chronos twice while inside the edge of the Chronos ult (and then walk out)? At 41:52 game time, as Bubbles attacks, his entire model is inside the Chronos ult except for his one foot. Armadon appears to be further away from the Chronos ult but is stuck.

I am just posing this question because I did not cover it in as much detail as I should have above as I am no expert on Chronos' ult and maybe it just appears that way. But it really did seem odd (aside from Take Cover not showing).
