...and what exactly would be wrong with that? Worst case scenario the BTA price goes to $10 assuming you're buyer 1001 and everyone else bought the $10 pack. You still get a heck of a deal.
1) Paid for Starbound and got it
2) Paid for Starbound a minute late and did not get it, may get a refund
3) Paid for Starbound, or the price defined by Starbound, after Starbound was removed from the bundle
People are understandably annoyed by this -
