Aliens Stole My Parents: Error Code 121:80eae277/ Teen at Uni

No mods, fully updated game.

I tried to play the 'Aliens Took My Parents' scenario in an existing household. The requirements for the scenario are 1+ adult sim, 1 teenage sim and 1 child sim, which is all good for my household. I clicked 'Play scenario', and it gave me options to play in a new household in an existing save, play in an existing household, or play a new household in a new save. I clicked Existing Household and was able to click my household to play in it — fine so far. As soon as I went in to play my household with the new scenario though, I got a pop-up message that said: 'The game failed to load. Error Code: 121:80eae277:a1097627. It is recommended that you relaunch the game.' So I exited, went back into the game, tried again about three times, exact same thing. Then I tried to see if I could play the scenario in a new household in the save, yes, all good. I then deleted that household, placed the household in Newcrest and tried to play it using Existing Household, to see if it was a problem with trying to play in an existing household. Again, totally fine. I then moved my teenage sim out of the household and into another household with an adult and a child to see if that worked. Error code 121 again. I'm really confused as to what could be causing the problem.

I've got the same issue. Tried with and without mods. Funnily, I've already done No Skills, No Problem and Proud Parent scenarios on this same household (it was created for the former and then I ran Proud Parent for it as existing). I also tried relaunching and restarting the game, I also created 3 backup saves and played each for a few in-game days in case it was some sort of in-game circumstance, but no luck with any of them.

Upon loading, the game does remove all funds and take the adult in the household into the "Abducted by Aliens!" rabbithole (and drop the child's grades?) as I imagine the scenario requires, but the actual scenario pop-up and goals don't show up.

Interestingly, the error does not create a LastException file in my game. Same code as Xeresfemia, except for the last string.

@crinrictsure, it's error 121:80eae277:88fc0fd0

@crinrict  Okay, will do! For the record, there are only two saves left (I was deleting them as I went along because I hate the mess!). One of them has the scenario "started" incompletely because I accidentally saved after, the other one is wihout the scenario so you can see the error yourself. Hope that helps!

So I did get an LE but the funny thing is that the game loads or me anyways but as you say, no scenario. I guess that can't be loaded because of the error.

EDIT: Your Teen is at Uni, right ? I wonder if that messes up the game cause it expects the teen to be at school and tries to lower the grades and can't.

EDIT EDIT: I tried to replace the teen with another and this didn't trigger any errors but I think it might be too late since the Scenario is already not properly added. It looked a bit different then before but I still don't have tasks. Do you have any backups still from before you added the scenario ? Maybe worth trying another family where the teen is still in highschool

@crinrictyeah, the "(wo ASMP)" save is from before the scenario was added! I tried it and then left without saving. The uni thing is actually a good shout! I can definitely try again after she's finished, she's only got a couple days left. Just didn't want my elder to kick the bucket before then lol

@HarmoniaChimera I think even if she's not a uni anymore, it probably won't work as she's also not in high school anymore.

The wo ASMP is the one that throws the error for me and also has a scenario icon. Let me try the other.

EDIT: Yup, that worked. So I guess it's the Uni teen that the scenario can't handle.

EDIT EDIT: I created a new bug report for this and merged the thread.
