A couple of different Aspiration errors

I am also missing the ability to write songs. Both my violin and guitar are at level eight where you are supposed to be able to write songs. But the option does not show up.

Try a couple of different things: I can't remember how I fixed it, but I either needed to have the guitar/violin IN my inventory to get the option or NOT IN the inventory. See if the placement of your instrument is the problem but switching between these 🙂

When I clicked the fish tank, there was no option anywhere to add fish to it. So I opened the fish tank and dragged five of my freshly caught inventory fish into the fish tank. Didn't count for the aspiration. Putting them on the wall worked though. As a side effect my sims got the stinky moodlet whenever they walked past the fish tank, as the fish were foul ☹️

Yeah, sadly the aquariums don't work for "mount or bowl."  What does work, weirdly enough, is to buy a cheap bowl like the "Fit4Fish Crystal Bowl" or whatever it's called (I usually search "fit4fish") and to put the same fish in the bowl and take it back out 5 times. I'd rather keep my exotic fish as pets in an aquarium than mount them, but for the aspiration you need to use the dinky bowls.

As for writing songs, I usually have to click through a whole lot of options and need the instrument to not be in the inventory.  I think they've moved it to a second page?

@paulawalters2011As for the bugged outfits, maybe this recent thread will help? https://answers.ea.com/t5/General-Discussion-Feedback/Bugged-every-day-outfits-Unable-to-fix/m-p/10873567#M57190
