So I've scoured the map and found 3 locations with beaver dams: tributary delta east of green ob, waterfall lake near blue ob, and the swamp region near the Aztec temple (north central). The swamp had the most giant beaver dams (about a half dozen) which is great for resources but every time I've checked there haven't been any beavers. Between the other two sites I've count about 8 beavers in total. Is that really all there are meant to be for this huge map? Am I just really unlucky with my spawns?
