villagers disappearing

 

 Villagers keep disappearing on my map despite the difficulty level of my map being "peaceful" and having torches everywhere surrounding the village where they were.

 

2 only left of 4 (what is very little if we observe that is a village). and i lost the iron golem too.

 

To reproduce the bug:

 

•finding a village populated with villagers

 

•spend a few days (from minecraft) near the village

 

•and view the significant loss of the villagers

 

Ps:I spent approximately 10 days playing survival mode and although I made trades with the villagers (which ensures that they don't lose their profession) but the number of villagers decreased significantly over the days. Maybe they're just dying somehow that I couldn't figure out. I don't know exactly what's going on.
