Still had the save, so to be precise: it was turn 3, at emyn.arnen with gandalf, 1 ranger, 1 men at arms, 1 spearman and a gondor hero 'damrod' who attacked me from the east. My army is the witch king, gothmog, 3 less orc, 3 lesser spearmen, 1 pit guard, 1 snaga, 4 scout, 4 archers, 1 spearmen, 1 warband.
Could be the capndan population script that upon ocupation?
