If anyone has ever wanted to use a wither for a farm like this you know what dilemma you run into. Everyime you log out the wither will despawn. Normally the way these farms would work is you would rename the wither with a name tag that way whenever the server restarts or the chunk is unloaded the wither wouldn't despawn. On EMC you can't rename a wither with a nametag. My suggestion is to add this as a senior staff service. Now the main concern with renaming a wither so it doesn't despawn would be the fact it could be used as a crazy powerful griefing tool, but in this situation if a senior staff did the renaming it could be manageable. This would also cost a decent amount of money, ranging from 20k-50k.A few requirements to avoid griefing:When PMing a senior staff member to rename the wither you must list the coordinates of your base and make sure that there are no other bases within 'x' amount of blocks.The owner of the outpost/base must give the okay for the wither to be renamed to avoid members of the outpost attacking it.Whichever player had the wither renamed name is recorded wherever and if anything goes wrong you can track whose wither it was based on location/server.If you have any add-ons that would make this more fair please list them. I think this would be a great thing to help the wood/stone economy!
