1 pointGood question, and can't blame one for that. Long story short, before I know how the patcher works, I thought more/less the same as you -- the installation might not working as intended, and without knowledge for once I copied the MOD file inside a mod archive and then paste-overwrite the existing one inside my modules folder. Fun times, lol. So in general it's best for one to understand it like this -- as DP stated above It still should inject the appropriate changes into that MOD. What happened under the hood is the installer make changes to the already existing relevant MOD/unk_m44aa.mod file on your end, and does not copying what's inside the mod's archive. The opposite happened when -let's say- you have a clean install of the game and this mod being installed first. You will then have empty modules folder filled only with RIMs, without any MODs. What this mod does then it will copy the [vanilla] MOD inside its archive to yours, and then inject the appropriate changes onto it. It's a necessary procedure for the mod to work properly. And to answer the question -- I can only say to install this mod at the latter stage of your build, which means after K1CP and any other mods if necessary. Hoped that helps. Cheers!
