Is it possible to add a group to a group. I did that a while ago and it wasn't working at all. I wasn't sure what the reason was, so I did a workaround.
Now I think it would be way easier to do it the first way.
Group group = new Group();
Group otherGroup = new Group();
group.addActor(otherGroup);
This should work, right?
So I figured out what was wrong:
I did override the draw method in "group", and I guess you have to call the draw methods of the children manually because once I removed the draw method in "group" everything worked fine...
The same thing applies to the act(delta) method.
All I had to do is call super.draw() and super.act() in the Group "group", now everything works fine.
