The groups section was recently broken. It still works fully I think, it just looks really ugly and has even more glitches than before (which was already horribly buggy)

You probably want your group to be known better though ... so having it on the last page is best for now. You can't move it, or search for groups, which makes them very hard to use. Probably your best bet is a save in game, or a thread on the forums (which is against the rules but I don't really care, it's like the only way to use groups anyway)

Edit: I thought I remembered a thread for this, you already have one lol
