Unable to progress in game because of legacy items

I haven’t played this game for a while and for some odd reason my inventory had 1000+ legacy items.
After I converted my legacy items I now have 200+ power units with nothing left to upgrade.

Does anyone know a solution for this?

Send a private message to Sarah247, or email the support team asking them to delete the items in your inventory.
As for the game, its completely changed now, feel free to message me if you need any tips.
