Re: [OPEN] [DU] Graduation Hat Stuck

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.61.15.1020
What expansions, game packs, and stuff packs do you have installed? ALL
Steps: How can we find the bug ourselves? 1) Sim living on campus gets married, moves off campus, starts family but still goes to university full time. 2) Last day of university falls on a Friday, calendar shows graduation at 11:45am following Tuesday (no holidays on this day.) 3) When notification pops up to attend the ceremony, click YES to attend.
What happens when the bug occurs? The sim gets transported to Britechester, gets put into auto gown, other sims/townies in gowns shows up, everyone happy then those townie sims vanish into building but yours does not, you can hear the ceremony is going on but there is no way to start the rabbit-hole event, you just stand there (you can interact with townies and objects so you're not frozen, you just can't start the ceremony.) There is no option when you click the building to enter the ceremony (only to put up or take down banners). Soon those random townies show back up minus their hats and everyone disperses while you're still standing there in full ceremony gown and cap and there is no mention of the ceremony, you don't get the photo or degree... nothing, it's like the game takes you to where the vent begins but it doesn't actually DO anything nor registers you as a graduate once the event takes place without you.
What do you expect to see? I expect my sim vanishes (goes into rabbit-hole event) to graduate then comes out with photo and diploma.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

As mentioned in description I get transported to the building (above) when I click yes I want to attend my graduation ceremony, and she is put into a cap and gown automatically, other sims (i'm guessing from her class???) show up also in cap and gown BUT my sim just hangs around, she doesn't vanish into the rabbit-hole event like the rest of her class does, clicking on the building gives me no options to attend the ceremony (only hang banner's, take down banners or attend eSports[greyed]) so she doesn't finish graduating. I've waited around and nothing else happens, her classmates reappear and then just go on their way but nothing happens to her. She doesn't get recognition as having graduated. She never gets her diploma, never gets her graduation photos nothing. I've waited it out for a fortnight even and nothing. 

Since my sim is unable to actually progress through the ceremony she isn't recognized as having graduated so I'm unable to get ahead with the job I was targeting and I have the option to apply for university all over again (via computer) like I didn't just go through the whole process even though my [j] shows this...

So frustrating and confusing and I regret buying this because this is the first time I've sent a sim through university only to have the graduation bug. I don't know what to do to fix this.

I had no mods during this process, I did try installing a mod cheat when I tried different steps to see if it would force the event to start (arriving at university early for one example) to see if it'll fix it for me but nope that mod/cheat didn't work so removed that. I've also done the wholeeeeeeeeeeeee troubleshooting steps you normally request like uninstall/reinstall, remove folders to repopulate new files, go back to an older save etc etc. Nothing fixes this. I've tried moving back onto campus (she is off campus), I've tried attending by myself, with friends and family and nothing helps.

I've read other bug threads and my bug is slightly different because

1) she doesn't freeze

2) she gets the invite to join the graduation (most graduation bugs are about people not even getting notified, I do get notified.)

3) the graduation does take place (you can hear it) inside the building, I'm just standing outside unable to get in there.

4) I have no mods installed 

5) I haven't changed any of the buildings. 

100% confused and unsure what to do now.

EDIT: So obviously a glutton for punishment tried one. last. time. Behold my sim singing to herself while everyone else gets to graduate ☹️ ☹️ ☹️

OH, also forgot, when I just let the days roll by past the non-graduation day my sim permanently wears her cap.

... poor girl, living in hope/denial she'll graduate.
