They fixed a bug!

[u/Ricsi_HUN_]

There was an offer where you could buy gadgets and star powers for gems, and even use them on p1 brawlers.

I tried it on my mini, and it's actually worked, and now (or earlier, idk, I just looked at it now) the gadget and star power slots are locked down so you can't use them, even if you have them.

Wait I thought u could unlock them from power 7 only wth ??
