Thank you for editing, I was planning on doing just that, but you beat me to it!

I am having a big problem with this in my Survival base, normal difficulty, render distance 24 chunks. It started with 1.2.0.18 and continues in 1.2.0.22. I kill all the unwanted mobs (outside my pens), but a few game days later they've built back up.

Screenshots. Overview shows my whole base looking north.

Facing East and Facing West are from 2 days ago. These were taken from a Creative mode copy so I could get shots from a height. I have drawn in the chunk boundaries fairly accurately (with 1 mistake erased).

After taking these pics I killed all the mobs, about 80 of them. The remaining 3 screenshots are from today, maybe 10 game days later. Note that the "From perimeter" pictures are too far from my pens for my livestock to render. The "From closer in" picture shows that the pens are actually quite full.

The mobs just seem to accumulate over time until they're literally crowding each other. I have tried watching from my roof, but the spawn rate seems normal. This leads me to guess that the problem may be that they're not depawning and the mob caps aren't being observed, or maybe they are depawning (making room under the mob cap) but not actually going away. I have tried moving 250 blocks away for a few minutes, which I believed should make them despawn, but they don't. Passive mobs don't despawn if they have interacted with a player, but as far as I know the meaning of "interacted" has never been specified in detail. Would encountering my perimeter fence qualify as "interacting with a player"? What about me being close enough to make them look at me?

During the days they were building up I have been mostly within about 5-6 chunks diagonally away from the overpopulated chunks. Strangely, the crowding only seems to happen in the chunks to the north of me. There are fewer mobs south and east, and my pens are in the west so they may be reducing natural spawns there.

This should probably be merged with MCPE-25514.

This should be fixed in 1.2.0.31, can anyone confirm or deny that?

I have confirmed it, but I didn't see anything relevant to this in the changelog. Why do you expect it to be fixed? Is there another source for fixes I can cite when mentioning this was fixed on the wiki?

BTW, this fix may also have fixed MCPE-25514 and MCPE-14467. They weren't identified as dupes, but I think they all had the same root cause.

Added a per entity type limit that only affects creepers and ghasts so they won't spawn if there's already a certain number in a 5x5 chunk area- no more overspawning of creepers & ghasts!

This report is especially about too many Creepers spawning in a tiny area.

Hi There Bemoty,
It doesn't seem to have been fixed, here's another screenshot

Sorry, the previous screenshot was unclear. Here's another

While there are fewer creepers than before, there is still a very large amount, considering it's peaceful mode... Perhaps the limit needs to be lowered?

This issue only mentions hostile mobs, but the spawn rate of animals is higher than usual too.

See my comment and screenshots above. They were all about passive mobs ("animals").

Spawning is a very complex system and difficult to balance, because it depends on so many variables (difficulty, lighting, biome, block type, mob cap, altitude, distance from player, etc.) and is arguably the prime contributor to the gameplay experience in Survival. But don't worry, the devs are actively working on the problem right now, as hard as they can. Our best strategy is to be patient and give them the time they need to fix it right, because if we.pressure them to fix it fast it will probably just end up worse.
