The Battleship is more difficult to correct that I previously thought, but I'm getting there. It's all because the guy who made it had to provide all these extra panels on the inside, which are probably there for collision detection in the game. I'm deleting as many as I can find, which makes the process go a lot faster. I might add that this may be the incentive I need to purchase the full version for the Boolean operations because of all the intersecting parts.
