What Happens?

As of 1.19.20, villagers will randomly lose ownership of their own workstation block, leaving it unclaimed. Due to this, villagers of the same profession will sometimes "swap" workstations. Green particles show up when this happens.

What's Expected to Happen?

Unless a workstation block is broken or unreachable, a villager with a profession should keep the claim to their own workstation, to maintain parity with Java edition.

What Does this Affect?

This means making individual booth villager trading halls impossible, as once the workstations are shuffled once, each profession cannot reach the other's workstation, meaning their trades cannot be refreshed.

How to Recreate?

Only tested on Nintendo Switch: Create individual areas for multiple villagers of the same profession. (It took about 6 for me to get results) Isolate each villager from one another and lock out any trade item from their list. Check back on villagers after a restock cycle. If glitch occured, trade will still be locked. Check example for a booth design that triggers glitch.
