Makayane over at TWC has fixed the "Old Demise" gate! image - Warcraft: Total War mod for Medieval II: Total War: Kingdoms
Warcraft Total War is a total conversion mod for Medieval II Total War. Our goal is to bring the Warcraft universe into a Total War game. This mod will feature epic battles with units from the Warcraft universe and a new campaign that will cover the events of the Third War and beyond.
Edit as of 2019-12-10- "Warcraft Total War: 1.6 Patch by Gigantus, including fixed "Old Demise" by Makayane.
Makayane over at TWC helped me fix the issue with the gate not working when besieging or defending the "Old Demise" custom settlement from Hyrule Total War, and created by the Undying Nephalim- the settlement is used for many of the cities and castles of the Dark Horde, the Horde and the Trade Coalition. The textures are different for the Horde and the Trade Coalition as compared to in HTW. The Dark Horde has the same textures as the Moblins in HTW though.
The gate had the problem where it would switch side to the attacker as soon as the attacker stationed troops outside of it. There where also some patfinding issues, due to some buildings on the path to the city. Makayane has fixed these issues for HTW where the city is used as the capital of the Moblins, and in doing so she also did fix the same issue in Warcraft: Total War.
