Same here. I had about 2700 on me and made ship customizations that were around 1300. When I clicked purchase the screen went away but no changes were actually made ad i still had my cash. I have a feeling if I had lots more dough it would have taken it from me using that mysterious hidden cost. Even though the cost is rumored to be higher than it displays, players are feeling ripped off. And since no one has seen a Dev response on it yet, the rumors are only gonna get uglier.
