WHAT?! How can you say that? Listen, after I printed out the coloured diagram I spent a heck of a lot of time with numbers and letters and combos and things. IF it had been a CORRECT coloured diagram, who's to say myself or anyone else would not have solved it?
What it all comes down to is this: Because it was FAR EASIER for folks to point their collective fingers and shout "obviously a bad DM" than to focus on the puzzle, none of us bothered to try as hard as we should've. It's a classic example of the Social Influence model and the Conforming Majority and all that.
IF more persons had focused on the PUZZLE and NOT the DM, we'd of had a solution. But somebody set a bad example and a lot more somebodies followed.
YES, there definately WAS enough info given to us by Roman to solve the puzzle, but we ended up defeating ourselves.
