So I have had these villagers since 1.14 in this configuration. I tested this in a creative world, previously so the villagers should be able to restock there trades and such. But I have waited up to 1 hour and several day/night cycles and the villagers have not restocked their trades. I went into a creative world and recreated the configuration and the new villagers do restock their trades. This is very inconvenient for me since I have only the villagers from the previous updates.
