Mobs & display

I have had problems twice with witches throwing potions at me and the game freezes so I can’t fight the witch off in turn I come back into the game and have died. I wasn’t able to get captures or screen shots of those instances. I also have had mobs spawning inside my house (which is well lit) pictures and captures what included. Also the items you hold in hand do not match the color of items you are using (example using lime glass and shows clear glass to the other player.)
