Same thing except I was down by Skyrim on the coast (Between Cherno & Elektro). Group of 4 of us got teleported back about 1K. We start running again and 3 of us get teleported but one guy makes it to Cherno. 3rd & 4th time 2 of us get teleported but 3rd guy makes it to Cherno.
Have to Task Manager to shut game down each time

A youtuber posted a video reproducing this problem.
It seems that when you look at buildings you GPU usage drops for some reason.
