The bug I found is that sometimes, when converting a world in a different version into 1.14 pre-5, The villages stayed the same than changing into the new village.

I thought I was going to convert my 1.13.2 village world into a 1.14 world.

What happened was that the villages stayed the same.

1.Make A 1.13.2 world
2. Find a village
3. Go into The launcher and launch 1.14 pre-5
4. Covert the 1.13.2 world with a village into 1.14 pre-5 world
5. This bug will occur.
