Issue (The better the description the better i can solve the issue): When we spawn a Servant there is no problem, but when we kill it the server crashes and cannot restart it unless we delete the "world" folder, it only happens in multiplayer.

Steps to reproduce: Kill a Servant in a multiplayer world
