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, I save them, but the number never increases. It feels pointless to upgrade my buildings if the tokens don’t work properly. 

Please return my missing tokens — it feels pointless to upgrade my buildings if the tokens don’t work properly.
