Animals are still respawning?

[Talamioros]

In previous versions, animals stopped respawning once you killed them and built over their area--either running power through, or even a lookout tower. Now, I've foundationed over the entire place where they spawn, and they're still constantly respawning on top of the foundation. It's getting annoying having to kill them every time I go past.

Did something change, and is there a setting I can use to change it back?

Typically only powered buildings block respawning. If unpowered buildings can block spawns, you need a lot of them. Cheapest thing to block spawns would probably be a street light. Plus it acts as a limited power pole.

Weird that near my Oil Power Plant the Alpha enemy respawned walking on the side of the building. I mean... there are only 24 active generators and a train, and refineries for fuel, plastic and rubber. The only one that did not respawn where the hatchers

They will not respawn if you kill them. But if they just jump off the cliff and are not dead, then you build over that area. They'll come back to the spawn point after some time. So you have to kill them for them to not respawn, not just build over the area.

Keep in mind any updates can cause respawns.(not always but have had it happen to me at least)
Was just an update today.

Another cheap way that used to work to keep them at bay was just a small section of conveyor belt.
