March Patreon Reward - the Second Correction (Patreon)

Hi Patreons!

Well, that was predictable - I jinxed the reward by saying I expected there to be no more corrections. Well, of course I was wrong. Many many apologies.

This email has the correct puzzles - the latest change (and indeed the only significant first change) were to Puzzle 4 (Disco Ball) and the total D arising from it.

I accept full responsibility if your time has been wasted,

Mark
