Changelog for Patch 1.800 (added 02 May 2017):

New Features
- Added new Build a Water Fortress ability. This enables embarked Builder Units to create Fortresses on water and claim water structures more easily.
- Added new Oyster Reef structure. Oyster Reef generate gold and population within your domain.

Tactical Combat
- Fixed 2 issues where units could sometimes shoot through walls and other obstacles without a line of sight penalty. So your dudes and dudettes are safe behind their walls now.
- Fixed an issue where entering combat would wipe extra move points gained from Death March. Allowing you to use Victory Rush to the fullest.
- Mind controlled/ghouled units now always have 0 move points on the world map after battle. This is intended as nerf strategies based on unit acquisition in combat.
- Mind controlled units can no longer retreat from battle. No more cheap summon stealing, sorry.
- Chaos Rift, Great Immolation and Great Stoning now warn the AI that it needs to abandon siege defense during tactical combat. Charge!!!

Balance
- If a summoned unit evolves, then the summoning spell will be cancelled, and the unit will become a normal unit with a higher mana upkeep. The mana cost is based on the typical cost to summon a unit of the unit's new tier.
- Fixed a bug in the random map generator when generating a map with teams enabled. Teams would always be generated counter-clockwise around the map, making it possible to predict the location of other teams.

Stability
- Fixed a crash when clicking the 'center' button in the 'structure captured' popup after the structure was razed.
- Fixed a crash that would sometimes occur when releasing a city or a dwelling as a vassal.
- Fixed a bug where items being couriered would remain stuck in the hero inventory when an AI hero joins by surrendering.
- Fixed a bug where AI attacked vassal city of friendly player.
- Fixed a bug where unit buffs/debuffs from global spells would sometimes vanish without any reason

- Fixed hang in PBEM when one human player remained. Now you can end the remaining AIs rightly.

- Fixed PBEM issue where player was not properly notified of defeat. This prevents a dead state that has you staring at clouds.
- Fixed PBEM issue when swapping slots in setup. So the host can now safely take slot 2.
