Still having this problem. I have completed the Lighting puzzles 3 times now. This time I took screenshots showing my AP before I logged out after having completed them today, and after I logged back in 2 minutes later. They clearly show the 4AP pt loss. So by doing the puzzles 3 times (12 puzzles, 12 AP), I haven't actually earned any of that AP but have apparently just been wasting my time. Oh also, the rollback of AP happens on logout, log back in, not on daily reset. When you log back in that is also when they show back up as uncompleted achievements, it is not happening at daily reset as intended. Sorry to be salty, I hope this is helpful. https://imgur.com/gallery/mFa3TD5
