I have tried many things, but nothing seems to work. I changed my landscape to ground terrian, I created a bioma just for the beavers and in the “Tag” I put “Beaver”, I created a spawn point and a zone of volume for the spawn inside the beavers biome, I let the game run for a long time , and no dams appeared. terrain with few elevations, almost totally straight … everything seems perfect but it does not work, it does not generate dams. Anyone else have any tips? Does the size of the biome or the spawn area influence? Can the spawn area stay within the biome or should it be left out?
