Chests, Furnaces, etc will not open. They only open after about 5 minutes. I am not lagging as I am at a steady 60 fps. I do not understand why this is happening.
Also, When blocks are broken, they do not drop anything. I have uninstalled minecraft and reinstalled it, but to no success.
Edit: I cannot drop anything or pick anything up.
Everything got reset after I have done it. E.g Break blocks, placed blocks
