The cropped hair didn't happen until after the Genoa incident, it didn't happen after she came back from Africa.
That's the weird thing - they've already gotten back. Jim asked the other guy how he handled Africa and he said "I wasn't carrying the kid", and Maggie now apparently stinks of alcohol on a regular basis to cope with the trauma. The hair thing doesn't seem to have happened yet, though, and as someone else said, the after-action legal review seems to have been held after all these other events in the season. Way too much going on here...
