No bug fix was made. Auto-follow after combat is working for me (with the latest versions of WoW and Jamba).
Make sure your setup is configured correctly;
* all toons have every team member in their team list (/jamba-team),
* all toons have auto follow after combat set (/jamba-follow),
* use different master for follow is not set (/jamba-follow).
Edit: Ah, I see you sorted it out, cool.
