2 years ago 1) Yeah, sewers are absolute cancer to the pathfinding.
2) Looking at the save (the bottle bug thing), it seems that going above ground is about 1-2 tiles shorter than going underground. At this level of error, the algorithm could have picked any. There's no "pathing cost" associated with using stairs. I could add one, like i do to force people not to walk all over farms unless forced to, but I don't think it's necessary.
for some reason instead of going directly between two pasture animals (when relocating) prefer to go via stairs to level above and then down
is this maybe a trick to speed up calculations since game stalls for few seconds (I'm guessing sewers are horrible for pathfinding) each time I move my spider horde to new pasture but that is fine ;-)
