I had an infinite breeder built in 1.13.2. It no longer worked in 1.14. There were two villagers in there that i had fed. In 1.14 i removed the doors since villages no longer use doors and I didnt need villagers at the moment anyways.

We updated to 1.14.1 and now the villagers are breeding despite only one bed being available. The bed is located one chunk south and one chunk west of where the breeding villagers are. They have bred up to 20 villagers so far. When i remove the bed it seems to stop but when i place the bed it seems to start up again(not 100% confirmed though due to rng).

All these villagers have no profession. The two who are breeding are both from 1.13.2. They are located in a ocean biome and are swimming in water with a half slab pushed into them.

The breeder i had built was from the video https://www.youtube.com/watch?v=iKxah_YU8JU

I built two of these breeders. One on the ground and one close to 64 blocks or more above it.
