For a while now I have been looking for solutions to be able to have some monsters in my zoo. Biggest issue I have faced it the butcher command killing any spiders or bats I might capture and rename, At one time Ubu's solution to this was to put a spawner in each enclosure so I can just respawn the three monsters I would want to have, the spider, cave spider, and bat. I already have one in the spider enclosure, but it only spawns pigs (which can be fixed by using a spider egg on the spawner). I have two other spawners on my res (another spider one and a zombie one) that can be "moved" to the bat and cave spider enclosures, and then set to the proper monster using eggs. Let me know if and when this could be done. Thanks!
