so when we make the enderman grinder we need to have a endermite so the enderman will be attracted to it so they fall down the shoot but the endermite and minecart de spawn after a while and ruins the whole thing making us having to find more name tags. is there a possible way that this could be fixed ?
Post these in the bug reports please.
Check out this link "https://www.reddit.com/r/Minecraft/comments/2pz6lt/is_there_a_way_to_keep_a_chunk_loaded_on_smp/"
basically there is a simple fix by having the chunks(the endermite in this example) rendered at all times but this could cause the server to lag drastically in some cases.
edit: check this video out which briefly explains how to extend the spawnchunkrenderthingy
