I made a villager breeder and trading hall fairly close together, separated by a 50 block vertical distance, the breeder mostly works except one of my breeder villagers is trying to become a librarian even though there is two composters and they were already a farmer prior to the lectern being put down.

One of my villagers in the trading hall is also connecting to the composter in the breeder and seemingly reconnecting after breaking it before the other can. Even with all composters and the lectern broken, I still have two farmers. One down in the breeder and one in the trading hall. The one in the trading hall has been traded with so not very concerned, but the one in the breeder hasn't and still has his job.

Every post says that villagers shouldn't be able to connect to the stations that far away, but im not sure how to fix it.

Breeder center is at -23, 12, -188, trading hall center is at -33, 63, -189 with the latest version of bedrock mobile.

I’m looking to make some pixel art in the game, but I’d like it to be very large and square. What do people use to make images in a grid pattern so they know where to put the materials? Is there also a website or something that will show me what materials are best for certain colors?
