Oh, I already got it taken care of, but thanks so much for the tip! I initially tried converting my note (back) into a PDF, but that didn't help at all. I'm glad I learned that's a thing, for future reference. :P
I play pretty much every RPG and a few board games in Notes, but I didn't even notice you'd used it until after I tried to erase something. That was pretty much the last thing I would have expected to happen!
It is SO impressive and inspiring that you drew/wrote all that in Notes!!!
