While currency purchased via Genie’s Gifts is not intended to be doubled by Double Campagin Currency events, we will still enable the Double Storm King’s Thunder Campaign Currency event for the week after this fix goes live.
I am sorry, I am not sure if every single ounce of corporate memory you guys have has gone out of the window, but genie's gifts have ALWAYS been affected by 2x currency. You cannot go back on something that's always been the case and hurrdurrr it with 'ohhh it's never been intended'.
If anything you should expand gifts to work on ALL legacy campaigns, and have the bags of treasure give actually useful currency to advance those campaigns: Looking at Caer Konig reputation and Fallen Dragon Fangs specificaly, especially after you decided that the time and effort taken to unlock the beginning bit of Tyranny of Dragons means squat, and it is INTENDED that mod21 undos progress for no reason. After promissing time and time again that mod21 was not going to set back any progress.
It's like talking to a brick wall sometimes.
