Just thought I would add a note here for anyone else getting stuck. I figured out that NMM .17 is the only one of the mod organizers that will handle the fomod dependency. I tested Vortex first and it simply refused to recognize the esls from a dependency point of view, so I ended up installing it in nmm and then copying the files over. After my game 100% broke I uninstalled the world and tried MO instead; this time I ended up downloading it manually, opening the zip and copying the correct files over. {I have Slocums, but not the arcade}
