Seems kinda broken.

These lines also needs to be fixed:
"<action type="SetAnimalPopulation" animal_types="bear" min="13" max="25" era_factors ="0.0 0.25 0.5 0.75 1 1"/>"
Remove first '0.' from era_factors.

<action type="SetAnimalPopulation" animal_types="bear" min="13" max="25" era_factors ="0.0 0.25 0.5 0.75 1 1"/>
Remove first '0.' from era_factors.

This needs to be rectified in the scenario files:
"<action type="SetAnimalPopulation" animal_type="mammoth" min="10" max="15" era_factors ="11 0.75 0.5 0.25 0 0"/>"
Change '11' to '1' to fix mammoth numbers.

I think you need to adjust the probability of animals appearing. The only change this mode make is the number of mammoth in the early game stage. I don't feel any changes in numbers of other animals. Played about 10 games with this mode so far, and never succeeded to hunt 5 woolly rhino. Animals still fades in time, I don't feel any increases in the number of animals. It's sames as vanilla game after neolithic. In conclusion this mode does not accomplish its purpose 'providing the option of remaining a hunting clan for longer, and seriously reducing your farm load.', It only helps you secure bone,meat and raw skins easily in the early game by mammoth hunting.

Will this mod ever see an update? or is it dead?

svp merci

I have just started with Biomass, I hope it solves the issue that was starting to make the game boring. It is, as you suggest, the disappearing animals that seem to impose starvation as a necessary part of the progression in every game. Worse, as I found my village nearing agriculture, even large animals seem to produce little. There is also a significant and concurrent problem with the drying up of dry skins, making it impossible to provide skins outfits and housing for the new population. As a result, I set my leather maximum down to 5, rather than using up dry skins essential for other purposes.

One thing I notice in the early stages of a new game with Biomass is an abundance of mammoths. These over-match a few villagers with only wooden spears. My experience with mammoths has been that hunting them usually results in a few villagers being killed. For the first time in any of the many games I've played, I spent my first winter relying entirely on fish.
Thank you.

even before playing this mod, the picture looks great!

@CCWARD12 - thanks for the information, I still haven't been able to track down what's causing it, but think its something to do with having no wolves until the Neothlithic era, I may need to just hardcode dogs in. Hopefully that will work.

It seems like the dogs dont auto generate?
