Trading with villagers and an odd movement

Trading with villagers bug: Sometimes choosing to trade with a villager will not work and the screen to trade may flash up for a millisecond but overall leaves the player unable to trade.

Weird movement bug/glitch: A lot of the times after you leave the interface of a furnace, crafting bench etc the way you were looking beforehand will have changed. E.g. I look down to craft something and when I leave the interface I am looking up. Happens quite often and is quite annoying.
