Started shipyard window, cleaned up console output, worked on Planetary Marketplace a bit. Turns out that buying and selling does not work. Selling seems to do nothing, and buying and selling do not update the credits of the player (and probably not the cargo hold of the player's ship either). In other words, the system needs fixing since it hasn't ever even worked in the first place. This is just shameful that you guys never implemented it properly even multiple weeks after the initial due date for that segment of the code.
