I tried to join a multiplayer game. As I joined the screen looked weird with icons and textures missing as if the character creation screen wasn't loaded properly. When I changed character all of the textures and icons loaded. There was, however, next to my character a man (human) with the starting gear. He walked around a bit and at one point I tried to right-click on him. This resulted in a pop-up where I could inspect and also attack. Clicking attack made the human (which was apparently controlled by me) attack the character I was creating (The Red Prince, in this instance).
Leaving the lobby and reentering seemed to fix the issue.
