Invisible Party UI - Doesn't show member as in party

Recreation Steps
1) Invite a member to the party, they should not immediately accept.
2) Load into your hideout - whilst loading, the party member should accept.
3) This will lead to the party member UI not showing.

Expected result:
Party member UI shows even though I was on a loading screen whilst they accepted the invite

Actual result:
About 2 or 3 / 10 times it would result in the party member UI not showing. This makes trades quite hard to do sometimes as I am not sure where the guy is standing.

I was unsure what to tag as this is my first bug report. I am not 100% sure that this is the reproduction, but it happened frequently to me when I invited someone, then immediately went to my hideout.
So I have to assume the recreation is somewhat acccurate.

Have a good day!

Да это ужас очень часто с этим сталкиваюсь

Have this same bug quite often, it's worst during trading, not many people will wait for you to leave the party and re invite and even then, sometimes the icon is still missing and there is no way to join their instance and trade.

same issue, often the party UI does not show, this is particularly frustrating for the already tedious manual trading

Same issue here
