Hi, could you make animals not die by mob removal? I always wanted to be able to catch animals in the wilderness bring them back to my place, to make a farm with them. Etc: Catch a sheep, get wool. This should be allowed, as this is one of the aspects in survival, being able to make a animal farm without a spawner. However, this will cause lag, But you could make it so any animals alive on our chunk will go invisible until we go back on line and maybe a limit on how many animals we can keep our house so we can't make the server lag. This will stop lag, and allow us to have a lovely animal farm without spawners, and be able to keep them without having to worry that mob removal will kill them.
I hope you can make my suggestion.
Thanks.
