I solved both Guardian 28,128 (Nutmeg) and FT 16,471 (Redshank) online. 17d in both puzzles had the same solution, and 14a (Redshank) had the same solution as 16a (Nutmeg). Looking more closely, both puzzles used the same geometric grid. Sharing a grid is likely not rare, as is sharing one solution. Two solutions plus the grid seems highly unusual to me. Or has lockdown completely addled my brain? I thought the puzzles might be authored by the same setter, but Redshank apparently sets for the Grauniad as Crucible.
