The new doors don't drop properly.
What I expected to happen was that the birch door would drop the birch door.
What actually happened was the birch door dropped a regular wooden door. Later testing showed that this happened with all doors
Steps to Reproduce:
1. Place any new door,
2. Break door in Survival Mode
3. Get regular wooden door.
