I accidentally launched without applying my Launch Discount, but Steam is graciously applying it anyways. The game will have a %15 discount for a bit!
"Folks who already bought the game won't automatically get a discount, but they can refund-and-rebuy at the lower price if they wish, and if any of them have already played so much of the game that they can't self-refund, we can help them refund and rebuy."
Thanks Steam, and Happy Birding!
