Both Hotbar and Inventory

I don't know if it is an intentional feature. But, one thing for sure, it's annoying!

can you show us how to reproduce it?

can you please take a screenshot of it?

This is not a bug. Armor Stand will change it's pose whenever it interacts with a block that is being powered(this includes powered rails).

This is an intentional feature. Nitwit villagers(villager that wears green coat) are awake at night and asleep at day.
