Bug Report: http://prntscr.com/mcyc1b http://prntscr.com/mcyc1b When the website loads, if I put in a large number such as 500 and hit the generate button, it does not clear the previous puzzle and overlays on top.

It seems to be some sort of canvas rendering bug as if I clear the canvas [1] it seems to work. 1: https://stackoverflow.com/a/2142549 https://stackoverflow.com/a/2142549
