Anyone heard of this??? lol?

ok my husband is due to ETS the AF in may, his terminal leave begins next month, yesterday he recieves his DD form 214, so he calls MPF......they are like where are you, hes like at work at my base, they said what are you doing here? you were due out on March 1st lol. so anyway he spends the whole day running all over base doing paperwork etc.....and they are now filing for him to be reinstated for 2 months, because someone somewhere put the wrong M month in the computer (fyi his orders etc ALL said MAY) they said since hes out of the system though he will have to wait and get his full months pay on 1 april, because he wont be back in in time to recieve midmonth pay. just wondering if anyone else has seen this happen?
