Game Mechanics: Group bug (group full when joining)

[Tetrian]

I have had this happen some times now - and its the same result every single time.

If a group leader invites more than the 5 people he can into a group and people then join, the individuals who tries to join after the group is full(gets no message about it), is left with the "follow" and "disband" button enabled, but is unable to disband or do anything group wise.

Meaning to basicly have to relog in order to fix it.
