Why are pretty much all of my cards grayed out?

[Adam Preston]

I can still open them, but it still annoying

Hey Adam!

It's likely that you have the "Card Aging" power up enabled.  Can you check in your power up list to see if that's the issue?

[Adam Preston]

Thats it. thanks!

[John McGovern]

we have found that card aging had been added automatically. We now have hundreds of cards, across many boards that are greyed out.

Is there a way to automatically turn off card aging across our account, using Butler or something else? 

[Julia Hindmarsh]

That has happened to me as well

[Michael O_Callaghan]

We found this happening when we installed and then removed a POWER UP for creating PARENT/CHILDREN cards and linking them. 

Still looking for a solution :)

Hope that helps.
