I have been solving old hypercrosses and came up with two so far that have Cannon lenses instead of the correct pictures.

https://www.tanga.com/crossword_puzzles/2099 – Clues 15 and 16

This makes it very hard to solve those puzzles. I have solved both by asking other Tanga members for help, but it would be nice if these were fixed for other players.

I have found one more that I have not solved with the same issue.
