Sometimes you may have the same problem like I had... ArmorStands, whether visible or not, do not want to get deletet.
With this plugin you finally can remove them.
Drag it in your server -> plugins folder and restart. You have to be op. Right Click on any armor stand or other entities you want to hard remove. Bingooo. they are removed. When you have finished,
do not forget to remove the plugin from you server !!
No commands, no permissions. Only available for players with op. Simple
PlayerInteractEntityEvent and
PlayerInteractAtEntityEvent. No messages. Its simple made as it is. Have fun :3
