60supply tokens for 1 event tokens and you need 30 to make a flyer. That means it's 3.6k ec per 30 event tokens. Still not worth making the new flyers.
30 x 60 = 1800 not 3600
Good luck finding someone with 1,800 supply tokens then.
Meh, I'll just wait for the next "patch" maybe Aga will reduce the amount of event tokens that is needed to make the new flyers just like he did on Dragonwagon and Hamster wheel.
