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
Hmm, this is all signs of lag. All of it. It's all happened to me on servers when they are slow and laggy. FPS can't determine lag, so it must be your operating system or something of that nature.
