A couple of different posters have pointed out problems with my “Monstrous Neighbors” and “Tactics and Towers” puzzles. The first had an issue where there were two equally possible solutions based on the description, requiring the hints to actually solve it. I moved those hints into the description and wrote two new hints. The chess puzzle was not possible, as castling is not a legal move to get out of check, so I have reworked the problem to still allow castling as a bonus move while the normal move of rook will still solve the problem.
