Weird pathfinding with horizontal ladders

It's not just ladders. They generally prefer longer paths instead of shorter ones, for some weird reason. Also when you have more than one of a building, they will often prioritize the further one instead of the closer one. I have a feeling someone somewhere inverted a number in the code by accident.

Another example of crazy pathfinding. Instead of using the ladder on the right all the way, they exit on abyssalite, climb where the Ren is and jump on the second ladder I am now deconstructing.

Have been having the same issue with Ladders vs floor tiles in configurations like the one in the first post. Was just simple floor tile vs long path of ladders beneath. If the top of the ladders were able to have a path that doesn't involve the hopping, it would be a touch more effective, but as-is it takes more time.
