[1.0] Copied myself with Cease to Exist

[Qwertycoatl]

I got an escort quest as a paradox mage, and cast Cease to Exist on some monster. After I killed it and time rewound, there were two of the escortee. One of them got killed by a monster and the quest failed, leaving a stationary version of the escortee sitting there. When I tried to swap places with him, he turned into a copy of me which didn't move but which shared damage with me (if it got hurt, so did I).
