I'll probably post this in Tech Support, also, but though I'd put this here in case anyone has experienced something similar;
Early Jan62 (Union) - issue orders. End Turn - and the orders aren't resolved. Some scripted messages are displayed again; nothing moves.
Back up one Turn, to early jan62, do it again. Same result.
Back up to Late Dec61 - Turn resolves. It is now Early Jan62 again. re-issue orders. End Turn.
And the same exact result again! No orders processed!
Anyone seen anything like this?
