Is this https://www.spigotmc.org/resources/armor-stand-editor.7688/ what you're referring to? I'm honestly surprised its out of date considering its native to 1.16 but I believe you.
If you are referring to https://www.spigotmc.org/resources/hebrewfix.52764/ It only goes up to 1.12 and may not work for minehut servers which are 1.16
Please provide a link if you can. If this is the plugin you're talking about it only goes up to 1.13 and may not work on minehut servers https://www.spigotmc.org/resources/idisguise.5509/
This plugin hasnt been updated for a few years. I tried finding an alternative, but only found paid plugins. I do know that essentials has a sort of player tracker that can remember the cords of where players last logged in if that helps
