The "Soulstone of the Wolves" still summons helper wolves underwater. Seems a touch strange. Call of the Wild can also be cast from underwater, not sure if that's an issue.

Has the Void Summoning logic been changed? I'm taking a -long- -long- time with a R'lyeh SP game (e.g. forced myself to clear all the indy-9 water provinces before making any serious push onto land), and my Starspawn summoner has never been feebleminded. Yes, there's luck dominion (something like +2), and the Starspawn is holy, with starshine skullcap and further empowerment, but it'd surprise me if the odds somehow went down to 0%. He has been attacked, however.

Heavy snowfalls can occur in an underwater province.

I once ended up with a preaching starspawn inside a fortress somehow ending up on the outside, besieging a (small) enemy inside, without a battle. The castle might have been cast that very same turn, and IIRC the Wild Hunt (which appears to attack as the owner's side, and not Special Monsters) attacked an enemy commander in that province that turn.
