I was trying to re-save a patch I’d edited with a different name. I got an error “can’t save file” (or similar, I forget the exact verbiage.) Then I could see my new file name in recents, but not actually select it again. When I scrolled over to the disk icon, the file name changed back the original name. I didn’t want to save that because I didn’t want to overwrite my original patch.
When I tried again without “>” it worked. Was that indeed the cause of the error, or was something else going on? I selected the character from the onscreen keyboard, so I’d think it should be valid.
