I had this bug too, I had much protection IV, mending and sharp V and eff V and fortune III etc.. all despawned villagers were at 1 location. But they don't despawn at my different trading location. Pretty weird.
Foxcraft is a network that consists of multiple classic
gamemodes like Kingdoms, Skyblock, Survival, Creative,
Prison & more. All of these gamemodes have custom
features that you won't be able to find on any other
classic gamemode server.
