Mods don't not work in game after uploaded to Steam, but work in editor

i found if i cook with the map NOT TheIsland but the name of the level you renamed after copying from GenericMod it does in fact cook with all the assets in the directory. In the level data forceload TheIsland and bam it SEEMS to cook right… however my mod crashes when i load it now so dont know if this is one step in the right direction or not…
