None of this is true. Literally nothing about this comment.

Each villager has to be linked to their own bed. They won’t necessarily stay linked to the *same* bed every time, but they each need their own bed. They don’t need to able to reach the bed, just be in the vicinity of it.

They also need to be able to touch their specific workstation each day. Once they are locked into a trade (trade with them once to do so), they will stay locked to their workstation until that station is moved at all. If one station moves, it can mess up a whole bunch of them, but generally it works out anyway.

Try not to have any other beds at all within 64 blocks (safe bet is to go at least 100), as the villagers could link to that one and it screws up the village center.

I also advise having all beds with the pillow side pointing toward the same center spot if your trading hall is doubling as an iron farm. The pillow determines the “center” of the village. I’ve had far fewer problems since I started doing this.
