So, as I move my items inside my inventory, they're looking normal. But when I am trying to use them, for example build a stone, it is disappearing miliseconds after using and block that was in this slot before is being placed. I can move things in my inv only when using furnance, chest and other things like this, even backpack work. My friends inv is working normally. In singleplayer and other servers everything is ok. It is actually super annoying. Any idea? And sorry if I am hard to understand, you know, I am Polish and not using English everyday.
