Samurai Persistence

I found the root of your problems; I'll tell you right away, the problem looks critical, but it's not a big deal. You can't upgrade the Coral Sanctuary not because it's bugged, but because it's forbidden on the map, and another building upgrade, which was added in Armageddon's Blade, is also bugging out.

Great, and how do I fix it? Only by removing the Armageddon mod? Or how? Since you're so knowledgeable about these issues, I have another question: I'm playing Heroes, and at some point, the game crashes to the desktop without any errors. I checked the error log, and it shows error 100, code 1001-1000, appcrash.
