Last night I went afk to play Terraria with some other members of the server and lost connection to the server while I was gone. This morning, when I came back to play MC I logged in and I was dead. I lost all of my inventory due to this, but that doesn't bug me, I just wanted to let you know that this has happened multiple times to me when going afk.
This has been happening alot recently, but there is one thing that may have caused it. if I'm not mistaken, Terraria started when you were in Athens, a PvP town...lol, are you sure you left Athens first? I make sure I'm safe before ever going AFK, or at least hidden in a place where nobody will find me. Spawn is not always a safe place, people will push you in the arena so you need to be careful. And, if you die, five minutes later if you didn't hit respawn it disconnects you from the server, that may have been why is disconnected you.
