I have 4 Kusagani level 1, and one of them is unselable.
All of them is ready to upgrade.
So i click the salable ones to upgrade.

But now my Kusanagi level 2 is unsalable.
And i have one salable kusanagi level 1.

Is it a bug or what ??
Because i already get so many bug now and i just to get some extra crystal by selling cards.

If you use at least 1 sellable and 1 unsellable card of the same rarity, the created card will be unsellable This is a rule unfortunately, not a bug.

Was there a way to pick the 3 sellable ones to make it to lv2? Because i have one simillar problem?

The only one i think is not to evolve the unsellable one to full XP
I know it's stupid... but it seems to be the only way.

Could you tell the staff that this is a bug ??

I believe not just has lost many crystal because of this.

Many of my cards are become unsellable because of this and most of crystal are from evolving cards. So this is a problem for people like me.
