This isn't affecting gameplay, it's just really annoying. I'm also a bit nervous that it may affect my Sim getting opportunities. Her phone will not stop ringing. I was playing, she got a call for a date, ended the call, but the ringing would not stop. I've tried silencing the ringer, changing the ringtone, changing the skin on the phone, did the obvious check to see if she was actually getting another call (she wasn't), none of it has worked. I figured it should resolve itself next time I play, I was wrong. After almost 2 weeks of not playing Sims3 at all, I opened the last save and the phone was still ringing. I've gotten out and back in two more times since and it's the same thing. None of the Sims seem to respond to her phone. No matter what she's doing the ringing continues, showering, sleeping, at work, it does not matter.
OK, the technical stuff. I have all of the EPs, no SPs. my last uninstall/reinstall was right after University came out. I also have Monte Vista, Aurora Skies, Dragon Valley, Riverview, Union Cove, and St. Clair installed. My computer is an Asus PC with Windows 7 Home Premium.
