I accidentally punched a wandering trader and it ran around like they do when hit. But then proceeded to open my iron door and go through.

Steps to Reproduce:

1. Build a small room
2. Add an iron door to the room
3. Spawn a wandering trader inside the room
4. Hit the wandering trader

Observed Results:
The wandering trader opens the iron door.

Expected Results:
The wandering trader should not be able to open the iron door.
