Bugged, as we suppose, because when you enter the room for the first time, there is only one beaver. In just 4-5 seconds there are already 3 of them, all spawned from the same point.
Even after we take down the entire pack, in a matter of seconds they start spawning as nothing has happened.
There is another bug. Sometimes beavers spawn inside logs and therefore cannot move. However, we cleared all the rooms and left no beavers behind.
I can also provide a video proof.
