With the latest release, the limit to how many counters (and stoves) you can put in your cafe has been changed. For example, in some cases, if you had 5 counters before and remove 1 to your inventory, you won't be able to put it back or put another one because the limit is now lower. You'll be able to put it back the next time your counter limit increases.
With the latest changes, you will receive Golden Favors from tournament rewards, and you have a chance to win Golden Favors from tasks your teammates complete. So, you won't be getting a Golden Favor from tournament tasks that you complete.
Due to the large volume of tickets about these matters, we are not able to answer them all. Thank you for your understanding.
