Pathfinding+island error

I made an island for my main base. I then made a bridge so that my hearthlings could get to the mountain to start some mining. However, after crossing the bridge and mining, they could not find the way back to the food crates. For a whole day i just saw the hungry pop up and they just ended up not doing anything. I used stone slabs/floor material for the bridge, i am worried that was what i did wrong. i also put a wall and door on the bridge for aesthetic/safety reasons.

Sadly i got so frustrated that i closed the game before i could save/screenshot the errors.

Also i tried using the pathfinding console command, but am not too sure how it works. if someone could explain that, i might be able to fix it on my own in the future.


were there actual error messages? or were you just referring to the problems you were having.
