Players can be forcibly resleeved into a previous character

Brief description of the issue

If a player dies as one character then joins as another, it's possible for the player to be forcibly resleeved into the old character.

What you expected to happen

An attempt to resleeve the old character would result in failure because the player had abandoned it.

What actually happened

The player was pulled out of their new character and into the old one. (This has happened to me before, but what prompted this issue was a recent ahelp from someone else.)

Steps to reproduce

• Die as Character A.
• Respawn and rejoin the game as Character B.
• Have someone find Character A and attempt to resleeve them.
• Watch your screen suddenly go dark while you're in the middle of doing something as Character B, and realize you're Character A again.
