TodayI went to Serebii's and Munching Oranges base, but all of their pals told me to come again tomorrow. I have 0 flags, yet both their flags weren't there? Why?
When you add a base with a qr code, you have to wait a day before you can get their flags and battle them. I think this is to stop people from farming flags and farmin experience by re-adding their bases. Hope I helped!
