For the past two days since skyblock was re-released, I have been trying to get 13 bookshelves. Every time we get animals though, they despawn before we can make any use of them. I have evidence of our animals, could we have them back please? It is impossible to get leather for these bookshelves (and I have been trying non-stop for the past two days) when the cows constantly despawn. I had to complete the expert farmer challenge 3 times and traded an enderchest for a cow spawn egg, and they're all gone before I could even breed them enough to get a decent pay-out. There's no way i'm farming for two hours to get any more cow eggs, and I can't see them spawning in this tiny patch of grass any time soon.
