5.4

Enigmatica graves
Basically the player died and upon death instead of hitting respawn was logged out of the game, Upon relog player could not respawn, after restart player could respawn but could not do anything but hit himself. Upon death player then became ghostlike and unable to access anything in the server.

Logs
Attached files I have. Had to go to a different modpack currently until fixed because world is currently broken. Don't worry, I'll be back,
