2018 WPF Puzzle GP Round 3 Announcement

We discovered about 12 hours into the competition that there was a PDF transparency mastering error that caused Puzzle 6 (the second Simple Loop puzzle) to print incorrectly on some PDF renderers. The puzzle always displayed correctly on screen, but, depending on the operating system and PDF tool used, could print with an extra unintended black cell.

The problem was discovered and corrected during the competition, with a replacement PDF uploaded.
