I haven't been able to replicate this in any form yet. I'm trying to think of a way of getting data/screenshots from you that will show what is going on, but since you don't know it's happened until after the event it's almost impossible to get before screenshots.

Could you take a copy of your game on the 31st December and then sim through as normal and if you find odd roster moves you can load up the other game and have a look there to see where the player was originally.
