Sims3 moodlet won't change?

my sim had to rummage through the neighbors trash & when she was done one of the moodlets said disgusted because of the pile of trash & that it would go away in 10 minutes. the time never went down though & its been there for a long time now. the other moodlets are fine. they go away when it says. does anybody know how if theres a way i can fix that?
