Player Bot?!?!?

[tweedjt]

okay so sometimes when i go to my spawn there is a Player just standing there frozen and no one can push them. when i check to see how long they've been on it says usually 4+ hours. So i decide ill kick them but when i use the kick command the server says they've been kicked but they're still there! Nothing works i try kicking from console or banning, but their name and character are still there! The only way i can get rid of them is by restarting the server. This has happened to me about 4 times now and they players all have different names. Anyone know what is happening and how i can prevent it?
