After constructing my first of 2 trading halls, I started to notice the Villagers restocking a bit more than what the wiki says. A similar issue had appeared in 1.14.4, and has been fixed.

They seem to be restocking 3-4 times a day, rather than the 2 times per day that the Wiki states it does.

Steps to reproduce:

IMPORTANT: Do note that I am not 100% certain that this is the exact way to reproduce it, but based on my experience, it seems to occur when I do the following.

1. As soon as they stock up, trade with them till you cannot

NOTE: I traded with them during work hours, which seems to be a contributing factor**

2. Once they restock for the second time that day, trade with them till you cannot.

3. They should restock for a 3rd/4th time

Things to Note.

1. They seem to restock for the 3rd/4th time during work hours
2. I have not tested this on any other Villager other than farmers*

EDIT: If need be, I can provide a video of me trading with the Villagers, as well as further information.
