I mostly agree with this solution.
In my opinion it was a faulty or bad design that provoke both errors.
Having a presale end with no notification its just wrong. I hope you guys learned from this. I know it was told in advance that it would work this way but you should have foreseen that this was going to happened.
People who didn't get bonus packs because they didn't imput the voucher amount BECAUSE the voucher slot never scrolled down should also be properly compensated and included in the presale. Lets face it whoever designed that sell page made a big mistake. I'm sorry I don't mean to be harsh but it really screwed over a lot of people. Things are supposed to be easy for the customer not this confusing.
If this was a consumer case in court the customer would win it 100%.
Dont get me wrong, I love the game, I love you guys but sometimes a little bit of harsh criticism can be good. Pleas take my comments as someone who wants the best for the game and its future.
