was on my survival world one night before 1.17.40 had villagers and animals now there all gone next morning when 1.17.40 came out.

i have a village with around 20-30 villagers mostly maxed out, 20ish sheep 7 cows 7pigs all in a 2 chunk radius, there was no lag. but the next morning there was a 1.17.40 update and when i got on all my animals and villagers were gone, villagers all had there own beds so they did not migrate. the only villager i have left is one i was transporting the night before and i stayed in the same chunck as the villager.
