I rolled back and rehosted turn 14, this time my movement orders went through ok. Everyone please check on your turn since it is bound to be different and report any weirdnesses.
I will leave it at turn 15 until tomorrow night midnight EST, since everyone who issued oreders for turn 15 will have to redo them. I will probably set the game to host at 12:30am EST instead of midnight just in case the host process is running afoul of some other scheduled event.
My movement orders did not go through either on Turn 14. Everything else happened other than commander movements. Looks like it was likely messed up for many people. No big deal to me, I can live with it.
