Players are using spawners, after a while the spawner gets full with ex. alot of skeletons. Standing and afking and letting it spawn hundreds of skeletons on 1 block. Which makes the server crash after a while, when there is overloaded with ex. skeletons. Any plugin to avoid this, I know there is plugins which makes multiple skeletons on one skeleton. But I dont want that, is there any other way then that plugin to fix this?
