Doing it on a single pc.
And as u stated, started with group of 8 then manually added 2 more to the group manually.
And i also switched som chars who hasnt been in the main group before..

So guess ill need to check the follower group setting.
And can u clear out old groups ? added all my chars by doing multiple groups so i got them added in isboxer.

Guess ill have a couple of hours to spend tonight to set this up

if this doesnt work ill try share my profile.
