unload and delete your /oxide/data/restoreupondeath_data.json

Hi k1lly0u your advice didn't fix this bug.
It seems that the plugin does not know how to work with groups of players.
It is necessary to give permission only to the individual for each player.
It turns out that the players with permission has no error.
