I am running windows 10, Intel Core i7 9750H @2600GHz with NVIDIA GeForce RTX 2060 @ 6GB (192bit).  I installed the snapshot, backed up my world and immediately took off for the nether.  I LOVED THE NEW NETHER.  REALLY WELL DONE.  I probably spent 3-4 game days in there and then returned to my village during daylight hours only to find that all but one villager had vanished.  There were 48 villagers and now there is 1.  All of the iron golems were still there and the village sits behind two security barriers so they did not all wander off.  I have been working on this village for 2.5 years.  Please help.  NEW NETHER IS AWESOME.  Please help.
