I've tried a few servers and on 4 out of 10 I had the issue that whenever and whereever I walk into a building (civilian houses, fuel station shack, etc)
and I try to run/walk out again my character gets teleported back into it.

I stood still for a moment IN the building and I got teleported as well. Felt like a lag BUT that does not happen when being outside.

So that has to be a client issue in context of server lags or connectivity problems.
