Possible minor bug
Encountered twice a minor bug.
When fighting an enemy soverign he used a spell I beleive called 'Ice shard' to attack a unit. This lowered the units action points the next turn. The next turn, once all my units had used thier action points they did not regain them each turn. Auto battle resolved the fight so a minor bug at best.
Oh and the creature summoned by the the empire spell summon spy has an attack that does a 10 point consistent damage to every enemy on the field including ones untargetable by enemy spells like darklings.
