Changes in Deer Multiplier when on Pacifist mode

Posted this in the Steam forum as well.

Usually, I play Pioneer on Pacifist and use the custom settings to max out everything but boar, wolves and fish. In game, ALL deer spawns are at max population and up arrows. The deer never run out. The spawn will still move if it’s built on, but it always has a huge herd of deer and max arrows.

I started a game on Pioneer with only Pests disabled from the DLC. I maxed the custom settings like always, but my deer spawns are all very low on population and arrows. I have one hunter covering two deer nodes and there are only like 3 deer on the map.

Is the deer multiplier connected to the other (aggressive) wild animals? Why the huge difference in spawn rates?

Perhaps deer, which eat your crops, are considered pests?
