So I've been playing around with some of the xml files. I've been able to create a new faction as well as create buildings that actually work in-game (thanks to all the helpful posts on the forum)!
But now I have a question: How do I replace an existing building with one that I made? I just created a nice Watchtower, but when playing I have the option to build both the standard watchtower as well as my own creation. How do I replace it?
Do I have to create a new xml? I haven't really worked on any xml mods before, what do I do?
