same as mine, it happened a week ago only in a specific village near my base(other villages is fine, we are managing 4 villages), i have tried switching servers and reinstalling ubuntu server 20.04 but it still causes the same issue and after several crashes it finally stopped then all of my villagers and traders near my base despawned even with the nametag RIP! right now im fine with no villagers than rebuilding all my structures
hey guys they just released a new version of the server, they said that the issues are fixed including this bug with the village
