I'm not sure this qualifies as an error, but it's aesthetically displeasing to me: on today's 7x7 no-op, there are multiple solutions (e.g., a cage with 2, 4 could be - or :). Normally I think of uniqueness of solution as a feature of calcudoku/sudoku-type puzzles. Agree?
If you got that puzzle as a bonus puzzle, it isn't necessarily visible to (all) other users.
This old thread (which has a now-deprecated link to an image of a puzzle at the start) has a thorough and interesting discussion on whether "unicity of operators" should be required of no-op puzzles. I think it depends on whether you regard specific operators (and not just the unique arrangement of numbers that satisfies the numeric requirements, using any valid operators) as part of the solution proper, which I don't. (I agree with what starling and sneaklyfox are saying in the thread and have even
argued in another thread that it shouldn't be required of users to fill in operators to get the correct arrangement of numbers in a no-op accepted as the solution.)
Anyway, all of this is somewhat off topic in the present thread, which is about problems with bonus puzzles as such (even if recent bonus puzzles generally tend to be no-ops). Feel free to post a new topic to revive the "unicity of operators" discussion, though ;-)
