Updated to version 1.1 implementing suggestions from StrikeR14 and Mr_panica.
StrikeR14: Thanks for sharing. I've added that method into the plugin. That's one less file server operators have to deal with.
Mr_panica. At your request players are no longer regenerated when they remove their clothing items. I was a bit reluctant to remove the regeneration. When you remove cosmetics like legs/feet items it will remove the leg and/or feet from the player model which makes the player look very weird with no legs. When regeneration is used the player model is made whole. But... as you noticed the player can use this to cheat, so I removed it.
If anyone has any ideas how to regenerate a player model without restoring health please share.
