Bugs that I encountered. (Return to session marker and UI bug)

In the first image I encountered a bug where the "Return to Session marker" will be stuck there till I restart game. It happened when I leave the yellow play area during the mission once I completed the challenges.

In the second image, whenever I switched server to join in my friend's party, it will create this UI bug. It will return to normal when I earn or spend on one of the currencies. 

A bug where I tried to invite my friend from my server to mine, it will not appear as so nor I cant re-invite them as I wont be able to let them leave the party or made them a party leader due to said bug. 

A bug where I still unable to see other players in the world including when I spectating them. I believe it's the server issue as my connection was relatively stable. The annoying workaround was to keep playing for 30 minutes till they all reappear.
