EDIT: gave your post a quick read and missed your point, however, I think unintended values for objects would fall under the category of bugs. I\'m sure we\'ll both survive given that this post is here!
I doubt Schema unintentionally made a typo in the block value; if he was that careless, the game would be far more crippled with bugs than it is now. The value is intentional. It\'s probably a placeholder too, for the time being. Or, ice planet rock is simply that valuable. Go figure...
