Gosh, this took me abnormally long. :) I was finding only 52s, whole pleiads of them (or 56s, like Valycian). Soooo happy to have finally found the 50, too. :)) It went from Bachelors to masters and now back to Bachelors, I see. :)) And Valycian got it, too, so it now has 20 solves, with mine, being the last one, atm. LOL Have solved some Professor levels, in the meanwhile, so really not sure, why this one took me so long. Darn checkers. ;)
