Since the last update 1.9 the temperatures of all the biomes were changed, the vast majority being less hot and now almost all the animals in that biome can live in it without temperature problems, an example of this is the grassland biome, the animals from the European pack that had that biome, when they were put in they had heat problems, but now it doesn't happen anymore and it's great, especially in the franchise mode, the desert still had good changes since they are not hot for the animals that live in it and so we continue with all the biomes, but not for the tundra, since before it was known for being the only map that was completely covered in snow, but now it is too hot that the snow is gone, and for the arctic animals that was the only place where they were always happy, now they have some heat and when the heat wave arrives, many of the tundra animals have heat problems, the temperature rose drastically, I hope that frontier cam Well, this is because at least in the franchise mode it is a problem due to the heat and the changes in terrain since, since it is always snowy, the animals that endured 100% snow were happy and now their terrain has changed completely and you have to put refrigerators for many parts
