npc stuck

version: 1.5.6 when i was playing with my steam friend, Shortly after their marriage, I found Emily was stuck in the blank place in my Upgrade 1 Plank Cabin and she was stuck only that space

I was messing around with chairs seeing if I could get through the door without being a friend and now robin has been blocked in and no longer spawns, dialogue is available when interacting with her door but nothing else happens. How can I resolve this

When I went to sleep that night and checked again, he was fine and in his normal routine.
