Noticed this while rep farming in Lost City of the Tol'vir. None of the rep gains were being reflected until exiting the instance.

The problem seems to stem from the fact that the UPDATE_FACTION event isn't sending a value for the unit param it's just nil. Commenting out the unit check in the event handler fixes the problem.

function ProgressBarModule:UPDATE_FACTION(event, unit)
    --if unit ~= 'player' then return end

    self:UpdateAllBars()
end

This will be fixed in 7.0.9, thank you.
