hi, i have a bit of a weird one, in a krastorio+SE run right now, lost nauvis to the biters, forced to switch planets.
Nauvis's biters were evolving into different rampant biters as expected, however now if i visit other planets, only generic vanilla biters seem to generate.
Nauvis also still has rampant biters on it, is this intended behavior as the new planets arent polluted yet?

although while i was still on nauvis, other planets DID have different levels of rampant biters, only as of recently, new ones seem to be all generic vanilla biters.

Any idea what could cause that?

Rampant-fixed ignores surfaces where biters are not specified in the nest auto-placement settings.
At one time I thought about introducing additional checks. But since on most planets that have nests this setting is set, the occasional vanilla biter on low threat planets is considered a useful feature, though not planned.

You can verify this by scanning some planet with a high level of threat (you will have to wait 1-2 minutes). Or by scanning more planets with a low threat level (then the surface can be removed) - some of the planets will be with Rampant's biters, some will be without

Well, the weird thing to me atm is, we had a pretty dangerous planet completely infested with biters (rampant ones, worked as intended), but we had to trim the surface later, having to regenerate the map at a later time due to performance reasons.

However at that point only vanilla biters appeared there.

Is there a way to force rampant biters to spawn there again instead?
Perhaps via console commands if needed?
Not quite sure it i understand the mechanics behind this just yet, regardless appreciate any help on that matter.

Hm.. also checked a bit further, seems like new planets seem to sometimes generate with only vanilla biters, but other times with rampant biters, that seems to then stay persistent as long as the planet is not trimmed/regenerated.

Basically just leaves the question, is the only way to ensure rampant biters in that case regenerating the planet, or is there any command to reload/regenerate existing biter nests?

Just checked.
Really. If you cut the planet without removing it, then the nests are not replaced when the chunks are regenerated. This is not what was intended.
I can recommend removing that entire surface - when you visit it again, everything will be fine.

The next release will not be soon, but I think by its release I will figure out what's wrong. The strangest thing is i don't get a similar situation on the starting world... Anyway, this is very useful information, thanks

There are no commands for this situation. Because I still don’t understand why the recreated chunks are not processed, I can’t recommend anything but delete the entire surface.

Yeah i didnt have any issue like that on the starting planet aswell, tried starting a new game, worked just fine out of the box, thats just some quirkieness that seemed to pop up over time, i assume probably not really easy to reproduce.

Regardless, maybe youre able to find something, would be great, otherwise basically rerolling the planet is a passable workaround, even if not the most ideal

Was just mainly not sure if the mod just outright broke at some point, but since it still seemed to be active on some planets, things were pretty uh.. intransparent :')
