I have my thirteenth letter in the last column after two ignored moves because they used previously used letters. The next moves are 3 E , 2 SW and 2 SW (a tricky one).
I have just reviewed the previous posts and I see it was suggested the message is 3, 5, 8, 4, 4. I found a 2, 1 instead of the penultimate 4 where the 2 is an abbreviation and the 1 is a letter serving as a number. To be fair I reversed engineered this segment after identifying the obvious last word but it seems to work and I still can’t find a four letter word for that space.
Should I have another look? It does not affect my final grid.
