[OPEN] [CHEATS] Skill Cheat Not Working To Lower Skill Level

I had the same issue several days ago with my toddler. Let me digress first...

On the September 11th/12th (before the September 18th patch) I was working on skills with my other toddler. A couple of the milestones were misbehaving for me by not checking off when they should have. One was numbers (and the window when the numbers flashcards appear was past) one and one was the top 'max movement' one. So... for both of those (thinking and movement) I used cheats to lower the skill so I could re-do part of it and get another chance for the milestone to complete.

I believe I used stats.set_skill_level Skill_Toddler_Thinking 3 to lower the Thinking skill from 5 to 3. I then looked for and found that the 'numbers' flashcards were an option again. My toddler did the numbers flashcards and got the milestone. I also used stats.set_skill_level Skill_Toddler_Movement 4 to then lower the Movement skill from 5 to 4. Then I had my toddler run around until the bar was almost full and the 'maxed movement' milestone appeared credited. I then put the stats.set_skill_level Skill_Toddler_Movement 5 cheat in to raise it back up to 5. However, it didn't show as 5, but once I saved, left to the main menu and re-entered it showed at 5.

Now fast forward to this last weekend, after the September 18th patch. I was doing the toddler stage in the exact same family and lot with the next sister in the family, who was now a toddler. When my max movement milestone would not credit no matter what she did, and her skill was at 'Movement 5', I decided to try the same trick. None of it worked. The cheats to lower the skill levels did not work no mater what I tried. 

I own all packs, play on Mac, and never use Mods or CC. My game is fully updated.
