puzzles have gotten harder lately

For the first few weeks after the Great Puzzle Rescaling, the system was giving me puzzles a fair bit easier than I was getting before (and no, I didn't monkey with the difficulty level — just left it at "normal"). And that was fine; if puzzles are for improving our OTB play, it seems sensible to train on puzzles that train quick pattern recognition rather than deep calculation. And that said, it seems like lately even the normal-difficulty puzzles have gotten a good bit harder. I don't care about my puzzle rating; I'd be happy to get slighly easier puzzles and if you must you can go ahead and ding me as bad as you need to, when I get one wrong.
