Survival item and block

Item and block glitches: I'm on update 0.8.0 that just came out, there wasn't an option.

A lot of the time my items or blocks in my inventory will have incorrect quantities that will say "99+" and gives me infinite resources. Same with tools, they will not ever break.

I also found a problem that I can't place chests. If you try, they will instantly turn to cobblestone. This happens sometimes with furnaces too.

Please fix this I can't really do much without a chest either =)
