this has probably already been noted, but just in case:
Wanted to rename my units (and a similar thing happened with a region, if I remember correctly), which worked in the OOB-screen. But on the map, my newly-formed 112th MG Bn was still seen as "2". Which is not surprising since there's no extra field for changing a number on the icon - but perhaps this could be an idea for the future?
Anyway, wanted to let you know that this is a fantastic fantstic game. Got a full-time job, still lost countless night-hours last week (which wasn't very wise but oh well
) - highly addictive, thanks for this!
