When a region is ruined, I found it very hard to get units out of the ruined region into new regions (i.e. by using chaos cards). So, what happens to units in ruined areas? Do they:
- Come off the board? (I don't think this happens, as it would render Nurgle's 'remove units card' moot)
- Allow units to move to a new region? (Unlikely, as the units only 'move' from your reserve to a region, or by intervention of a chaos card, e.g. teleport)
- Do something else?
