[OPEN] [LAST EXCEPTION] AttributeError: 'SimInfoBaseWrapper'

I'm getting this error as well. It seems to occur most frequently when clubs are gathering, and everyone attempts to change clothes for an activity (such as swimming). It will result in everyone wearing the wrong outfit for a given activity. Oddly enough, sims will still remove clothes for showering, but won't put them back on which leads to a lot of involuntary streaking...
