So here's what happwns. I use the mod install tool. The mod get put in to assets/mods/before the fall. So I think all is well start a new game and nothing no changes. I assume that the opening screen of the mod has changed because I looked through the mod folder and see new opeing screens etc. So this is why I think the mod is not working. So then I try to manuel install the mod and I copy all the files to the assets folder and copy over the duplicate files. And the game crash. So whats going on here?????
