Hi My In Game Name Is Warriornefth I have found a bug in Minecraft 1.14.3 pre-release 1 that consists of villagers not path finding or getting a profession as soon as you generate you world. It is likely to see a normal villager nodding its head because of no profession when there is a profession block next to it. As it says in the summary this issue usually eventually gets fixed due to being in the area and villagers wandering around but it take a while to find its profession. I am pretty sure this isn't a problem for me only because this has happened multiple times when generating a world. (my first actual bug report) Peace -WarriorNefth
