Animals slowly gathering at the edges of the map

[Wizzy]

As the title suggests I have noticed as i progress in the game that all the wildlife ends up around the edges of the map and none in the center.
I play with mods so potentially there is a conflict somewhere, i was just wondering if anyone else had noticed this?
The only thing this really affects is hunting/taming  as the pawns spend half the day traveling to the other side of the map.  But i'm more curious about if anyone else is experiencing this ?
I did consider maybe i was wiping the wildlife out and as a result more were entering the map from the edges and not progressing further into it. But i only ever have the auto manger select animals to be hunted to fill a specific amount which isn't much so i find it unlikely.

Didn't you have heat wave or something like that? When temperature exceeds some threshold, all animals will flee the map and after that will start returning from borders.

I've experienced as a result of a heatwave in the past but this happens with all of my saves. I'd say around half a year in and they are all around the borders.

I think it happens because new animals spawn near the borders. There is enough grass for herbivores there, so they have no reason to move elsewhere. Since all herbivores are so conveniently packed together, carnivores too have no need to move.

It's "caused" by animals spawning - so, basically anything that kills the animals. Hunting, toxic fallouts, cold snaps, heat waves, aging.

Good observation, didnt really spend much thought on that, you dont notice it much on smaller maps. This is due to how spawning works for animals and plants, and certain events kinda make sure they always stay at the edge.

Temperature events on maps with hot or cold tendencies can drive creatures off the map, toxic fallout kills every creature, overhunting does the same. Same goes for plants, huge fires (flashstorm), very low temperatures or the toxic fallout can kill most of the plants on the map, everything starts to grow at the map edge again and thats where hungry animals will gather.

I guess we would first need a new plant spawn algorithm that picks a few random spots on the map and then regrows stuff there, that would solve the food problem, then something that causes animals to move into the middle or to a random spot on the map. As far as I know thrumbos are the only creatures that move to the middle, would be cool to see if other animals were to do something similar. I guess theres the bottleneck called performance though, I could imagine a waypoint for every friggin squirrel would increase the lag in later stages.

I've had the same thing happening in many of my saves as well.

This also lead to some really stupid things happening, like 6 muffalos and 5 elephants waking up at the same time then stacking up on top of each other as they ran from a single patch of grass to the next patch of grass.

There is the screenshot of said clump of animals.

Ha nice screenshot,
ive never had it where there all on top of each other exactly they are all just clustered around the edges and dont really move inland.
But as suggested above i dont suppose they really have any need to ass they have sufficient food on the edges of the map where they spawn and predators will follow prey as they are obviously the predators food source.
The only thing i would query is that i didnt exactly feel like i wiped the other animals on the map out to the point where they had to re spawn. i never killed all the animals around the center  for them to respawn on the outskirts. Ive never observed it enough to confirm but it feels as though they just congregate around the edges over time

I mean, you don't have to kill the animals. A lot of things cause death, and most of them aren't controlled by the player.
Carnivores hunt and kill other animals. Animals die of old age. Existing animals can go manhunter (which will almost certainly lead to their death). Wild fires kill animals. On some maps, especially Tropical Forests, infections kill a lot of animals (animal gets hurt by something - forest fire, for example - the wound gets infected = guaranteed death). Cold snaps/heat waves/toxic fallouts kill everything alive.
Sometimes it only takes one boomalope to die of a heart attack to snowball into a small catastrophe, where animals burn to death, and those lucky enough to remain get infected and die. Players don't always notice such things, but it still leads to new animals spawning and staying near the map edges.

Also when a non-pregnant female animal spawns, all male species rush to it, which leads to male species "migrating". I doubt it's really noticeable but it may be a part of the problem as well.

I'm sure you've hit the nail on the head there i hadn't really considered other predators and what not killing the other animals off.

Then as mentioned above when they do spawn there is no reason for them to move inwards as they have what they require on the outskirts.
