[FIXED] Mischief skill achievements suddenly unlocked on load

and to test an older save too i just launched a save i played a week ago to check this issue and yep it unlocked the achievements (all my Sims  are YA's )

edit to fix image

Added.

Very reproducible

On the older save, it only seems to affect only my Miller-Couture household, I loaded Goth and those two achievements didn't unlock. It also occurs on version 1.8.

Recently received two unearned achievements:

Received the "Problem Child" achievement, but my Sims (six Sims in two different households) are all young adults - there are no children or teenagers.

Received the

achievement with my Doctor Sim,

.

No CC or mods
Digital download version, pre-ordered and pre-downloaded.
Outdoor Retreat, Get to Work, Luxury Party Stuff, Perfect Patio Stuff
NVidia GeForce GTX 550 Ti, driver version 353.30.
Intel i7-2600K CPU @ 3.40GHz, 8GB RAM
Windows 7 Professional, Service Pack 1

Confirm "Problem Child" achievement bug. Although I had children sims, but their mischief skill haven't reached level 10. I cannot confirm "Autopsy-Turvy". You really cannot know if that was an alien. Sometimes you receive a notification that patient organs are placed not in the right places. Without that examination you won't know. They could resemble humans because of genetics . I have received the achievement after the surgery.

@Thanks @RolandasR1. i didn't realize that the second achievement that I mentioned was real. It looked very suspicious to me - happening as it did right after the unearned "Problem Child" achievement.

I had the same thing with one of my Sims - I don't know exactly when it happened (it was quite some time ago). But I happen to have saved that Sim/household for other purposes and whenever he's placed in game and his household is loaded it completes the Problem Child and Master of Mischief achievement. His mischief skill is 1 and he has only ever been young adult.

This Sim happens to be on the Gallery, so I don't know if it may help fix the issue if someone looks into the files? Anyway here's the link: http://www.thesims.com/en_GB/gallery/E8D1DB71E9A811E48495780525D3AA9B

I do also have an unplayed version of this Sim - the one that autosaved itself to the library after I made him, he does not have this bug. So it occurred somewhere during gameplay. It was in my GTW test save - this Sim was/is in the Detective career. I don't recall having run into the issue in any of my other saves, at least not recently.

I do know that something concering the Problem Child achievement was "fixed" with the May 4th patch http://forums.thesims.com/en_US/discussion/832123/may-4-patch-notes Not sure if it has any bearing on this, but just mentioning it.

I have this one still locked on my current game so I believe this to be fixed

Any feedback ?
