Effects and mobs not rendering/loading

There are issues in maps/boss fights where effects or mobs just didn't load but they can still kill you even if they are literally invisible.

For example, I was doing the Xesht boss fight and the hands that slam the ground were literally invisible for a while, and killed me before they even rendered on my screen.

This is just a game breaking bug and it hugely affects the integrity of POE2 pinnacle content.
