In a LAN subscriber + host configuration, This happens randomly but happens enough times that i believe it to be a bug. It seems to happen more often than not when the subscriber crashes suddenly (i.e. close the APP without exiting). When you go to log on to the host again, you appear with an empty inventory in a single place, and always in that same place (in my case it is deep in a tunnel I once visited days ago).

After about 180 seconds, the host will somehow "figure out" that the subscriber is spawned incorrectly.

Then the subscriber will instantly get a "disconnected from the server" message, and once he logs on again to the host, he spawns correctly.
