Deletion of Inventory, Reset to Spawn, Skin Change

Put the summary of the bug you're having here

What I expected to happen was...:

I was on a multiplayer server hosted by a friend, and relogged in order to de-aggro their dogs, and was expecting to log back on with my items and character skin, in the same location.

What actually happened was...:
When I logged back on my inventory was empty, I had been moved to spawn, and my skin had changed from my custom one to one of the defaults.

Steps to Reproduce:
1. Play on multiplayer, hosted by someone else
2. Hit friend who has dogs (I think I had wheat in my hand?), get chased and attacked by dogs
3. Log off and log back on (direct connection)
