I'm not sure if this technically counts as a bug and it's not a super important thing.
I'm trying to remove duplicate minions from my zoo since they don't stack and that drives me nuts. It was going fine until I got to the second page. If I remove a minion past page 1, instead of updating that page it pushes me back to the first. Which is a big pain in the butt and resulted in me removing a minion I didn't want too.
