Minecraft sucks - months progress gone - 100+ gold and diamonds gone?

You would think it would be an important thing to tell the player that items disappear after a few minutes. What logic is that? An item lasts forever in a chest, but when taken out of a chest it will disappear after a time that is not instructed to the player? When moving my chests (since this games designer was incompetent enough to make you have to break the chests to move them), every single one of my items is gone. Now all I have is 3 things of dirt, 64 cobblestones, and 2 swords. Seriously, after playing every day for months and getting hundreds of gold, diamonds, thousands of torches on reserve, pickaxes, etc, what incentive would I have to ever play this game again? I am beyond infuriated at whoever designed that aspect of the game. All those hours wasted exploring empty caves just to find gold and diamonds. The one damn time I give PC games another chance, **** like this happens. I can't recall anything like this happening on a Nintendo game - if only they would make more than 1 game a year.
