There was something off with the Toolbox file that was released yesterday. This was not something I could catch as it did not have the problem in my game. Sorry about the inconvenience.

if you use any mod that requires Toolbox and updated Toolbox yesterday, re-download Toolbox.

I also did a small update of Group Invite Sims by Category (& View Sims by Group): flexible group invite system for menu improvements, But that's optional.
