Compared to the JAVA edition of the game, buildings have different probabilities of generating, depending on village type.

For instances:

1. A weaponsmith shop is more likely to appear in a Taiga village.
2. A pen is more likely to appear in a Plains village.
3. No fletcher shop in a Plains village.
4. No stone mason building in a Savanna village.
5. No shepherd's house in a Savanna village.
6. No lamps in a Savanna village.
7. No lamps in a Taiga village, too.
8. And no accessories in a Plains village.

I entered many seeds. Villages seem so different from JAVA edition. That's crazy.
