Dupes get stuck in bizarre places

This actually happens a lot. They might fix it at some point to where the dupes just jump from higher ledge since they fall anyways with no damage.

But it basically happens when there is nowhere for the Dupe to go and something is made above them, or below them I believe. In the case of your Dupe in the pic, he might have made the tile underneath him which pushed them up. He couldn't go anywhere to escape, so he got stuck inside. It's actually pretty funny and I am sure it's intentional to a point, seeing as how the Dupes squirm and are animated for when it happens.

Nope, the lower room have been finished already, then I've marked blueprints for the upper floor. There was the chunk of the fallen sand in the corner of the room, which I've marked for digging right after planning was made. This explains where the ceiling tile have come from (built by Olive, standing on that chunk) and this explains how Olive could dig out that hole, but it still doesn't explain how she got in there.

it seems like she somehow teleported there in the moment when she was building/adding materials to that spot and at the same time someone dug out that chunk of sand under her feet. That's where the bug is. Case closed.
