Just tested it out with 3 more groups , with 2 weapons, no weapons and 1 with no Armor, just my Pick, all worked fine but the Pick group, it saved the group but did not reload as naked and a Pick (the way I made the group) I am thinking that's the way it should be :)
FYI,Here is what it saved for the just Pick Group.
<group name="Dig">
<item createTime="1498076845" serial="5199494" slot="HandL"/>
<item createTime="1498076845" serial="5199494" slot="HandR"/>
</group>
Another thing I noticed is that the xml file is NOT saved until you log out. I even waited for the in-game save to happen and the xml file did not change to show the new Group until I logged out.
Also I changed the xml file so it was not proper just to see what would happen, the game would not load. So be careful if you change it with a text editor.
