This is a very minor but consistent problem is have been having in my game, I have played the sims 4 since it has been released, I usually have 1 sim in my household that has the piano skill. At one point when you used the action to play concerto, the sim would play consistently and the action would loop and would not automatically cancel. At some point this changed. Whenever my sims do that option the green meter goes around the action circle and it usually fills up very fast, typically canceling the sim playing mid song. I really enjoy the piano music and I wish I could figure out how to fix this. I have tried various options and nothing seems to help. I feel it might be a glitch in the games files.
I have also noticed recently that the guitar "jam" action which is the equivalent to the "play concerto" action is also timed now and having the same problem. I honestly dont know how to address this?
