Hi, Simsane! Thanks so much for the "praise shower!" We had a lot of fun reworking the game for iOS and Android.

There are two types of in-app purchases in VV Origins, consumable and non-consumable, which are set up differently on the respective app stores and are treated differently within the game. The consumable purchases (food and tech points) are "used up" as you play through the game - the villagers eat the food, and the tech points are used to purchase higher tech levels and other in-game goodies. The non-consumable purchases (the two doublers) are permanently associated with the user account that made those purchases, and they should continue to be active even after you start a new tribe, play on another device associated with that user account, or delete and reinstall the game. Depending upon whether you're playing on iOS or Android, it may take some action on your part to "reactivate" them.

First, you should have a look at the Upgrades! section of the game and see if there's a checkmark indicating that those two doublers have already been purchased. Let us know if it's not there (and what device you're playing VV:O on).
