Please fix grouping tool, lots of issues after update

Hard to invite, can't accept, invisible groups for leaders, can't pass crown.... you name it, we got it! Even in grahtwood zone people are asking why they cannot group. Doesn't seem to be everyone, but seems to be a lot. You have to rezone to see the group if invisible (though that doesnt' always work). Sometimes relogging helps. But this are desperate solutions that don't always worked. Please fix this. It's become rather problematic.
