Garrison Missions

They don't seem to be working. I can't finish completed ones or start new ones.

e: ...s\Blizzard_GarrisonUI\Blizzard_GarrisonMissionUI.lua:1769: bad argument #1 to 'min' (number expected, got nil)
Time: 09/02/14 21:16:15
Count: 3
Stack: [C]: in function `min'
...s\Blizzard_GarrisonUI\Blizzard_GarrisonMissionUI.lua:1769: in function `GarrisonMissionComplete_SetFollowerLevel'
