(hinterland_) undestroyable buildings?

[Count Armfelt]

Hello, I want to add Templar and Hospitaller guilds to Jerusalem and Acre, and so I edit the descr_strat, make Acre to a Fortress and add a minor hospitaller chapter house there, then I go ahead and add a minor templar chapter house in. So I start up a campaign and check that the buildings are there, great! Now I will surely have the orders waiting for me once I reach Acre and Jerusalem.

Once I take the settlements I find that the Templars guild in Jerusalem has been destroyed (probably by those damn Egyptians). So now I wanted to mod it so that the buildings are indestructible. I am told to add a hinterland_prefix, unfortunately I have no idea where to add it.

So that is my question: 1. Should I change the guild_templars_chapter_house to hinterland_guild_templars_chapter_house? 2. What file(s) should I edit? 3. What entries in those files should I edit?

Pass, but from sound of that you might get further if you ask in M2TW forum :

LOL.

Add it to the building tree name not the names of the levels.
