O wait, I misinterpreted an error. Yes, checking reclaim space worked. But then I had a network hiccup that made me think the disk was still screwy. Fixed the network and now things seem happy.
@__aru I should mention the blurry icon thing might just be the cursor, I didn't ask for a picture before they left but if you see the same behavior just let me know. Game scope got a recent patch to change how the cursor works, so it may just be a simple launch option change for the higher resolution display
