[MCPE-272] Animals sometimes never respawn in a map

I've been playing the same survival map for well over 24 human hours. Sometimes in peaceful mode, sometimes not. I originally killed all the animals, especially the sheep since I didn't have a bed or sheers, or because the wool was white and I wanted a respawn for other colours. They never came back. Cows/Chickens/Sheep/Pigs - I have 0 of them! I've tried closing/restarting the game, no luck. I have iOS6, FYI.

Have you tried exploring you entire map?

More than a few dozen times. I would estimate that a good 50% of it is water. There's a dense strip down 1 edge of the map, and another strip down the opposite side (so a massive river running down the middle). It's a very flat map, i've explored every inch of dirt, and even ran through all parts of the water.

FYI, I created it with the seed name "palace" which was a map I saw listed on "Minecraft Seeds Pro" iOS app in the "creations" list. I got the same map, but without Palace he made.

I just started a new survival level with seed name = "palace" on an iPad2 (friendly mode on). I immediately killed 4 sheep, 3 cows, 6 pigs, 3 chickens. I then swam to the other side of the map and killed 2 more sheep. That's all the animals. I've walked around the entire map 3 more times in 30 mins, and so far have not encountered another animal. Do you know the rules and timings for animal respawn? I really hope this can be fixed, I put so many hours into this map.

I'm going to check this out today.

As a test (to make sure it wasn't iOS6 related), I created another survival map (friendly) with seed name 1234567890. I killed all the animals on the map. Within 20 mins of walking around, a new batch of animals started spawning. So it's clear to me that there is something weird on seed "palace" which prevents animals from respawning. I hope you're able to find the problem, so I can resume playing "palace" map when the next update is released

Thanks for the awesome description. There where actually several bugs that made this happen and I still have at least one left to fix.

What are you rules for animal respawn? If you kill a cow, should it spawn another cow? Or does it spawn a random animal? The map i've been playing for the past 20hrs (seed: rainbow connection) started with a lot of cows. I killed all the cows/pigs for food, and currently have 13 sheep and 7 chickens. No cows/pigs. Is that normal?

If you kill a cow, it will spawn a random* animal (*Mob types have different probabilities). The rules aren't that direct though, but rather; if you free up enough "animal slots", a bunch of of a certain type will spawn. I've begun looking at this bug anyway.

true' I have killed all my animals in one of my maps and now my only mobs are hostile :C

Reported again on 0.5.0/iOS in ~~MCPE-816~~. Can't confirm or deny on that platform; not reopening this as ~~MCPE-816~~ is not verifiable (no world attached).

Restricted to global-moderators

Can a developer comment on whether ~~MCPE-1950~~ / ~~MCPE-2090~~ might be a regression of this bug? ISTM that the spawning rules have changed to try to spread mobs out more, and people are mistaking this for mobs not spawning. Is that the case? I haven't been able to reproduce the no-spawning behavior, should we be asking for world uploads to verify?
