Even after factory resetting Deltamod from the most recent GameBanana release, it shows this, crashes, and then still shows a Steam install in the install manager; this was after clicking "import from Steam" and hitting Deltarune. It now claims that there's already a Steam edition already imported after restarting Deltamod
