I agree with @Stormkeep about releasing all the packs and bugs. My sims discover more bugs in the game than the fun things to do. @Pamtastic72 I finally had to go to ModTheSims and download one of their upright pianos. It is an older one that I believe was made in 2018 or 2017 and it works wonderfully in game.
I keep hoping the team will also do another pack refresh/update like they did with Spa Day. That would be great for bug fixes too take a pack that is buggy go through all the issues people have and update it. Then work from there. No pack will ever be bug free, because we all work with different computer systems, however, I do believe they can make it better.
