You know... I'm not entirely sure anymore. My game obviously isn't reading a ModTechTree.XML file I just implemented and I cannot get the game to read it no matter what. My Traits Mod is working alright but I cannot get the new one implemented. I'd appreciate some help with this too... maybe the patch did something?
Also, I think mods are read BEFORE Core data... this implies, to me, that the core files get priority over mods. That's my theory anyways...
EDIT: Just noticed this
The hotfix will force the player to start with the new data, ensuring validity of key components (read: less crashy).
So, my theory is that it has something to do with the patch. It's late though, I'm going to sleep.
