PvPLogging command not working

I was pvping at /warp pvp against WhatDaFoxSay and I was winning my fight against him. However, as he ran away, down the stairs, to escape, he logged out of the game, however he didn’t die. Is this a bug? And, more importantly, I would like to note that someone else (MrRambinho) came in afterwards with full prot 4, however I got out alive but at that moment when I left WhatDaFoxSay conveniently came back in and he got out alive with all his stuff. Maybe another account of his or a friend? I dunno. Just putting it out there.

If it is a bug, then can I please have his stuff. I would have easily killed him if he didn’t log out and the person came along. Thanks for reading this.
