tried out A20 today and I am unable to interact with any loot. Basically the E button does not work. I've reset everything too. I also have this weird small black block window that stays on my from the beginning. I had hoped these problems go away after doing the Tutorial, but they persisted. I'll be switching back to Alpha 19.5 until this gets resolved. I was so excited to play Alpha 20, but it's made the game virtually unplayable. I would also like to point out that the developer drop down screen keeps popping up randomly while in-game when loading chunks. Sorry, screen shot is not working so I can't provide pictures atm either.
