I just completed a campaign, and when I go through the retirement dialog and hit OK, nothing actually happens, and I can't advance the day -- it just compels me to do the retirement dialog again. I can hit cancel, but it still asks me to do the retirement roll with every change of day.
Also, the GM box on the retirement dialog is greyed out :[
The bug was a result of trying to remove the unit for unassigned infantry.
Fixed in [r2104].
