There's a mod I've been using for Shogun 2 that I want to edit some aspects of (mod being Ultimate Immersive Mod) that involves changing the startpos such as me wanting to make some of the many clans he added vassals of the major clans. I tried modifying things with PFM comparing what other clans vassals look like and replicating what I see with the other clans but it appears to do nothing and I have no idea what half the fields even refer to anyway since there's only the values in PFM.
I figured I'd try the assembly kit but I can't find any way to load a mods files. So my main question is how exactly do you load a mods startpos file into TWeak? Is that just not possible?
