If I click on “Train” before a fight, all of my 2-star champion characters have the arrow next to them even if they are at max level and I don’t have covers available.
Is this because they have “0” out of “0” shards and they are erroneously thought to be ready to upgrade?
I came here to the forums to ask this same thing. All of my champed 2* characters have a flashing yellow ‘train’ button, but there’s not covers in my stash waiting to be applied.
