OK, something weird just happened. I went back to the buy tech screen and decided to see what 'exactly' it said when I tried to buy the food doubler again.
This time though, as soon as I clicked on the button to go to the buy more tech points, a screen popped up saying Please wait, updating account purchases. Then I saw the normal screen with the top option being to buy the double food, etc. It still showed the 99 cent price instead of a check mark. I clicked to buy it and instead of saying I already have it, it showed me my Amazon points and or the buy with actual cash.
I didn't buy it cause my tribe no longer needs it, but that's just odd. Now it's like I never bought it. I will look at my Amazon purchases and see if there is any evidence that I bought them. Maybe I'm just completely losing it, lol!
ETA. Nope, I'm not losing it, thank goodness!
. It shows I bought both the food doubler and the tech point doubler on May 8th. But Amazon is now willing to sell it to me again at least, lol!
