Small Business venues blocking San Mychuno festivals

After buying the Business and Hobbies pack, one of my sims bought the Art Center in San Mychuno. Then another sim bought the karaoke bar. Both lots were turned into small business venues. After a while I realised that the festivals were not there. The festivals in the other neighbouhood were showing up every time. After I sold the venues and turned them into an Art Center and a bar respectively, the festivals showed up as usual.
