Hi all.  I have two heroes leading armies, both with the CO skill, and both armies are losing health each turn in winter.  I'm in neutral territory, no retaliation tower is involved.  I think this is the first game that I've seen this happen in.  I did some searching, I know CO had issues in the past but the last post I saw on this was from 2015.  I assumed it had been fixed by now.  Any ideas what might be going on?
