Party/More Possible GPQ Specific Glitches

Description of the bug: (optional screenshot/video):
The following 3 all took place during GPQ runs on June 12:
1. Party members were not showing up on other players' screens (i.e. on the stage where you have to drop the offerings to the statues, the person dropping the items would be invisible on the screens of other players).
2. Party members HP bars would show as 0HP above their character (the bar would just be blacked out as if they had died, note the players did not die in the course of this run beforehand).
3. In the underground walkway portion of GPQ, some players had no NPCs show up on the map and could not interact with said NPCs. See screenshot below:

What is supposed to happen?:
1. Party members to show up on other players' screens.
2. Party members HP bars to reflect the accurate HP of the member.
3. NPCs to show up on the map and be interactable.
Where did you find and/or notice this bug?:
Found during GPQ - a few members of the run said they could not replicate the party aspect glitches outside of GPQ.
A step-by-step guide to re-producing this bug (optional):
Seems the party glitch aspects were not able to be reproduced outside of GPQ.
1. Not sure if it's just party specific as we only had 6 players for the GPQ, but seemed to happen after entrance to random players during GPQ.
2. Seemed to happen to everyone in the party, but each for a different party member upon entry of GPQ.
3. This one seemed to be a one-off and random per party member (possibly could be replicated, but only 3 players were able to advance to this map due to the already identified map glitch).
Extra information (optional):
Happy to give extra info/insight that other members of the run had if needed. Unfortunately, we only have the one screenshot.
