Failed Floor 4 of Trial of Sekhemas due to possible Latency.

I just want to scream. I don't know if this is a bug but I only experienced this in Trial of Sekhemas and nowhere else.

Everything just froze, animations still running, and then a few seconds later I'm dead. WTF GGG, I'm trying my best not to rage.

All that effort and hour+ of my time, GONE. Now I have to go through all floors again, hope that I get some good boons, and pray I can get to the last boss again.
