I first noticed something was up when Watie and Quantrill were stationary during the replay and dug in, despite having been given movement orders. I believe other movements failed to show up in the replay as well. So I loaded the last turn's orders, checked Watie and Quantrill - they ended up where they were supposed to go. But then I looked at the date - last turn was Late February. This turn, the date is Late March. Other than the replay being wonky and units digging in, the orders seemed to have processed all right, but apparently North America had a collective seizure for 15 days in 1863
Yellowhammer is the host, and I've asked him to save the relevant files (assuming he still has them) so he can post them here.
