Don’t Update Your Minecraft Just Yet
Minecraft 1.7 and 1.7_01 both have problems with the game crashing and your Minecraft save file becoming corrupted when trying to use pistons. This is a first time for Mojang since I’ve started playing Minecraft. Many of us Minecraftians were waiting for the many new and exciting features that 1.7 would have given us. With luck not too many save file casualties have occurred.
