Glitch/bug on stairs pathing

[Blackcat]

I placed a stairs down and used it to mine a area. After I was done I mined behind the stairs and place a new stairs and deleted the old stairs. None of the npc including the dogs could find a path out. Even if I forced them into battle mode. Restarted fixed the issue.

Hard to get a sense of the issue without images. If it is possible and easily reproducible, do let us know and if possible screenshot. Thanks!

I will see if I can do it again. I can also go to that save and try and reproduce it.

Kinda sounds like you cut off their exit.

I went back to the save for that. I did everything I did before. I took screenshots ( have no clue how to paste them, but they are linked to my account and are public) but the bug did not repeat. So I dug a long trench put my stairs at the end. Realized that to go down 3 levels I needed a longer trench. So I dug 4 behind my stairs placed a stairs the same way. Then destroyed the original stairs. Then the bug happen. They acted like that stairs were not placed. I restarted and it worked. I changed nothing.
