The Bug
On some woodland mansions, the illager face on the 3rd floor staircase can sometimes be exposed to the back of it. This usually happens when the carpet path on the 3rd floor extends to beside the back of the illager face on the 3rd floor staircase. This renders a noseless illager face appearing in front of the walls.
Steps to Reproduce
Create a world with the seed
1022401459.Execute the following command to teleport you to the affected woodland mansion:
/execute in minecraft:overworld run tp @s 10859.18 88.99 35047.64 17457.66 7.20.Observe that you’ll find a noseless illager face, with a normal face behind it. It means that the illager face on the woodland mansion has been exposed behind the walls during generation.
Observed Result
The illager face on the 3rd floor staircase gets exposed behind.
Expected Result
The illager face on the 3rd floor staircase won’t get exposed behind.
