Beavers Keep Getting Stranded

[What button do?]

While constructing an L shape strip of housing on the side of a mountain, beavers will constantly go between the housing strip and the mountain, and get stranded after the housing strip is completed. There are no resources between the housing and the mountain, it's literally 2 squares of nothing.

I have noticed that beavers will step out of paths for 1 to 2 blocks and idle when they are not needed, but if there's a building between the target idling spot and the path, they'll literally run around the entire building to idle behind the building. I'm guessing some times they'll idle behind the construction site, thus getting trapped once the construction is complete.

Maybe let them idle on the path? or have better overall pathfinding.

In this case, I have to destroy and rebuild the last housing multiple times, each time hoping none of the beavers idle into the back. Took about 3-4 times, quite frustrating.
