Multiple of my decklists have become corrupted, somehow. When I try to open them, I am launched into an infinite black loading screen. I've swapped devices, used both my my laptop, and my desktop, and I cannot access the decks in either. I've tried duplicating the decks, and the duplicates are also unaccessible. I'm extremely bummed, because I don't have these lists saved anywhere else, and I've spent a very long time fine-tuning them. I don't think I could recreate them from scratch. I've waited for upwards of twenty minutes on this loading screen.
