The bug
Zombie villagers with Gossips (from being a normal villager previously) do not keep their Gossips data when the world is saved and reloaded (on singleplayer).
How to reproduce
Have a villager with some Gossips
Convert the villager into a zombie villager, the zombie villager keeps the Gossips from before
Save and quit the world
When the world is reloaded, the zombie villager no longer has the Gossips
