I'm trying to alter the values on a few things in the mod, and I'm running into a few issues. I was wondering if I could get some help, if this is the right place to ask for it. I am using the latest patched version and my mod list is in order. I've already changed some things in the gameconfig.xml (the X-Division one) successfully, like soldier stat ranges and the like. The issue I am running into is with the buildings.xml and the aircrafts.xml. With buildings, any value I change is not reflected in game (trying to change build costs or Living Quarters capacity for example). Is there another file I need to alter for these changes to work? With the aircrafts.xml, it seems like any value I change (e.g. plane hp or loot for shooting down UFOs) in there causes the game to crash when I try to build my first base upon starting a new game. Again, I am wondering if there is a correct way to alter these values or if perhaps I am altering the wrong file. I am using Libre Office calc to make the changes if that makes a difference and yes, the files I am changing are the ones in the X-Division mod folder. Any help would be greatly appreciated!
