So more IN-DEPTH Details of sleeper

Before you guys comment yes i’ve read the posts and yes i’ve done everything ,but I am still curious when my friend and I were leaving he crashed and as he crashed/logged out his body just vanished! Right as he logged back in it reappeared. What could this mean? Aren’t you just supposed to stay there when you log? Also when you log out on a sleeping bag does your body vanish or is it still there for someone to come raid you or get inside your deteriorated house

I would imagine that the coding with sleepers/staying while logging off is still a bit buggy considering all the random lag spikes on most servers. I wouldn’t bother with this much atm.
