The same thing happened to me as well. Double payout was not honoured. I spent diamonds to buy more stars so that I could use it but I only got one of the revealed present (spice trader). The moderators have refused to refund the diamonds or to honour the double payout. They have told me that 'it is supposed to work like that' (that if you do something else between the double payout showing and claiming it, you lose it). I have said:
1. it is not good practice to do that: players would expect a double payout to be honoured, not avoided for a spurious reason; but
2. if that is what they want to do, they should clearly tell players that is the situation, and it would prevent us paying diamonds or doing other things to expect the double payout to be honoured; and
3. when players complain about 1 and 2 they should be more sympathetic, especially at this time of year.
What does it cost the organisers to be nice about this and give us back expended diamonds etc and even a consolation prize of the item we thought we would get double of? What it has cost them for not doing so is bad feeling, bad advertising and bad reputation. Come on Innogames: you do not want that, do you? Surely the way ahead is clear: you have a great game and a huge following. Give us a Xmas present: even if it is given without admitting any sort of liability, a gesture of some sort is appropriate.
