Prom duplicated and graduation inexistent + other issues

Hello,

yesterday I had the issue of descriptions/labels/interactions not showing up (in any language) for anything related to the newest expansion: world, cas, interactions and actions.

a colleague of yours through Twitter suggested to clean the cache on Origin - I followed the instructions as per EA official article.

It seemed it has solved 98% of the issue, e.g. some visual stuff were still missing but at least the game was playable.

Today I found myself with the following bugs/issues:

1. Prom is showing up in the calendar, along with other events, every Saturday. My Sim is really going to prom every Saturday [pic attached]
2. There is no way to prepare a Promposal - the invite can only be requested (not all the times) and eventually received through a popup, but then the outcome does not get saved.
3. Even if the Prom is concluded, there is no Graduation day (nor in calendar, nor mentioned). My Sim can only graduate early if agreed (meaning no ceremony).
4. My Sim does not get invited for the college party (she never ever received a call about it) and she cannot sneak out from the window - the window seems cannot be used to go in/out regardless the party/sneaky mode.
5. My Sim cannot have a teen job and following cheerleading/chess/football/etc activity at the same time. One excludes the other. Is that intended? I had the feeling that teen sims could have a (teen) job and do extracurricular activities too.

Any insight? It's driving me crazy.

Thanks in advance for helping out.

Any addition info you may need, I'm available.
