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.
Intended. Villages loaded from 1.13.2 and below and upgrading to the newer versions, the old village structures will stay the same. To find the find the new village, you have to go further blocks away in order to find the new village structure.
However, villagers will have their profession skin and their same trades as from 1.13.2 and below.
