You can continue where you left. Dont do the sets you already did. If you dont have the tokens, close the app and open it again.
My case is all the sets are open...tokens I think I got them all back but I can't restart since I don't already have the 87 curry...
After they restart the event I only got the shoe...
I'm currently holding the 102 curry or do I remove the card from my lineup and put it in the 103 Curry as part of the set?? maybe I'll try that out...only have 1 shoes though
