I also hit that bug last night in a new game. I’m using a20r699. It happened multiple times, with tables and chairs and beds.
Oh, and when there wasn’t another item waiting in inventory, the game waited until I recalled the original item and then a hearthling placed it.
However, with a fence that I’d done wrong, this worked correctly. I was able to move the pieces out and then back in the right order without them moving to inventory and back. And it didn’t pull new pieces out either.
I have also had this bug and it only seems to happen to buildings that are unfinished. As long as the building is finished it shouldn’t effect anything.
@Omegasa Sorry, but this was happening in a completed building as well as one that was waiting for the last couple of windows. It actually made the finished building change and say that it wasn’t completed and needed the item to be complete - when that item wasn’t in the plans anyway. I don’t usually do buildings with furniture included. It seems to work cleaner that way.
