Error
I have 4 Epic Buildings that give tokens to speed up production. Every time I receive tokens (for example, 3 gray and 1 yellow), they disappear and are not added to the total amount. I don’t use them...

You can only collect pieces of this tokens. If you look at your Screenshots
you can see a cicle above the tockens you have. When the cicle is fully coullered you will get one.
