Hello there. I would like to let everyone know about about a problem I've recently seen with mob grinders. When people afk at their grinder or mob spawner, it causes a build up of mobs that effects the entire server, causing lag, and causing mob spawns across the map to not work right. Today i teleported to an afk person and was immediately frozen from the lag. There were over 1000 mobs sitting in a single grinder. This kind of lag is not needed, and i took the liberty of destroying the mob spawner that was being used. So, try to be smart, don't afk at a grinder, and don't let your friends afk there either. Also, turn your grinders off when not in use.
