Members with the 'provisional Rank 7' still count towards one of the needed votes to leave an alliance, but are unable to actually vote during the provisional period.
This can be fixed by demoting them to rank 6 temporarily however this causes their 14d probation period to have to be reset.
I would suggest to change the Leave Alliance option to only require the votes of the full rank 7's (the ones who are able to vote)
