Entities Out Of Order is your issue. that is a game bug 

a few suggestions to fix this is:

1. restart server
2. failing that, kill the player and give him his items back
3. failing that, wipe the server

Merged post

looks like this might be caused by calling SetParent, even though it shouldn't. a test for the fix is in the works

thanks a lot
