If an animal is leashed to a fence or a cobblestone wall, you are unable to place anything on the fence or wall.
Steps to Reproduce:
- Leash an animal to a fence or a cobblestone wall
- Try to place a block on top of the fence/wall
Nothing can be placed on top.
The lead shouldn't prevent blocks being placed above.
Screenshots/Videos attached: Yes
It looks like the lead_knot hitbox is perhaps too big, or interfering with block placement.
