Meh, i've been following diff games news and announcements, just projects im interested into, and one mmo a year or so ago, had an official *14 days* transfer period, before some new patch/addon release. And guess what. Shit happened, and they took 3 extra days at least in the end to fix that bs, if my memory serves me well.
This couple of days is still nothing compared to that, so who cares. Migration is a process, when same kind of bs always happens, and take 2-3 days of your life. Be grateful to Allfather, u r not the one to clean that crap)
