Also having this issue in Bedrock XBOX v1.19.73. I've used the farm for months with no problems. Villagers (librarians) now don't stay linked to workstations, and when they have a linked workstation in the 1x2 space with particle effect, they still don't reset trades, even after several game days. I've reconnected workstations at least 3 times.
