Yesterday, the co-owner of my server was messing around with these new "only 1 command vanilla mods" in a flatlands world named sea on my server while I was away. So I come back to the server and find that the server is at 15-10tps (it's usually at 19-20) I teleport to his last location and go in spectator mode to find: (this was yesterday, I'll take a screenshot as soon as I find it again, imagine around 1000 invisible armour stands floating in one area) That seems to be the main source of server lag. /lag shows that the sea world has around 3000 entities in it. So I did essentials /killall all sea but it doesn't seem to kill armour stands. I don't want to delete the sea world as it contains many builds that would take a long time to copy over to another world. Does anyone know a command that kills invisible armour stands (or all armour stands) OR unloads chunks?
