Minor issue/annoyance of mine:
In my Romani campaign I have now twice had invisible, non-locateable Carthie armies/FMs siege cities of mine, which forces me to reload since I can't sally with my army since there is no army present! I even tried to find it using an outside army the last time and while it presents the red areas that should indicate where it is sadly those red zones seem to indicate an army that would already be in the city!
