Hey guys, my first post btw, just beat the game and now im lookin to mod it. Sooooooooooooooo i figure a good way to start learning how to mod is by making a mod that allows me to save during combat playing in impossible or hard mode. Yes i know kilobaks has already made this mod, but might as well try it myself just to learn Anyhow, I opened the Difficulty Resource tab, changed the CanSave value in impossible and hard mode to Always, hit the Update Game Data switch, Hit the build switch, Turned on SS, Loaded mod, started campaign..... and could not save in Impossible mode. Have tried this LOTS of times. Could someone give me a clue?
