After curing a villager with a locked trade they stop working at their work stations. This makes it so they cannot restock their trades and not allow the player to receive anything after the initial cure.

To recreate the bug:

1. Set a villager with an easily accessible trade like iron for tool smiths and lock in their trade.
2. buy all their stock to confirm they can restock properly
3. infect and cure the villager after they restock
4. buy their stock up after cure is finished
5. wait to see that they don't work at their job block at all to restock their trades

I have tried to fix this in every way

• removing and replacing every block of the villager
• moving the villager to a new location
• reloading my world, the game, redownloading the game, restarting my PC
