I was playing as a guest on a non dedicated server and we had an issue with my SCUBA tank breaking right at the entrance to the cave (through the water tunnel to Viking bay). We didn't know what we were getting in to, so we aren't geared for what I think lies ahead.

I logged out and forgot to get out of the shallows and died, but it would not let me log back in or let the host invite me back in to get my corpse and stuff.

So here's the question, can you use the ghost command to leave the caves (I think it's carnivorous cavern but we haven't actually seen any enemies). Alternatively CAN you log into a server when the host is in a cavern?
