Blueprints, too.As far as I know there are the following rewards for the recurring quests:
* (large and small?) coins package
* (large and small) supply package
* medal package
* 5 of one good
* medium FP package
* diamonds
What are the probabilities of getting these rewards?
correctFor each recurring quest in every age, you can win Diamonds ONE TIME. After that you get medals instead.
or 100%after several rounds the percentage is 0 for diamonds (verified for Iron Age)
