Group Dance Mod Broken by Up date Patch

The group dance mod that has been around forever, seems broken by yesterday's update. I know the creator was Shimrod. Also that Aariancya did an update on it, but don't know how to get in touch with them. So I'm posting it here. Help. When you try group dance with a group, only one sim (lead sim) will actually do the group dance. Other sims stand around and watch. Without the Mod in, sims will do a group dance but it's the shortend version of the original group dance. This is such a great mod, it seems a shame to lose it. Please help me to get it fixed.....
