I'm going to be honest in saying that whoever moderates the KSP subreddit needs to be removed from their position and replaced. Protest all you want, but do so in a way that doesn't effect others. Following a ridiculous tend and throwing a hissy fit that does nothing but bother the users is completely irresponsible and immature. From someone who's supposed to be representing the community, they make themselves and all of us look like foolish teenagers.

Make sure you have the MechJeb part on your ship. It's under Command and Control.
