I've also had numbers 2 through 8 happen to me. Although on #5, I like to stockpile weapon heads on the shelves and when I saved the game, closed it, then reopened it they returned to being "hot" which I'll assume is their default state. It was annoying to have to cool everything back down before I could use them.
For #9, crystals aren't implemented yet, he's planning it for update 0.1.2
For #10, yeah it says "Al Rights Reserved" on the title screen. Also notice that in windowed mode the title bar at the top says "My LIttle Blacksmith Shop"
