Heyas, My game & NMM worked well until last night when the game's started a loop: Launching starts the Steam window, then the game's launcher window, but hitting Start makes the game loop back to the start (Steam window, launcher, etc.). All I'd changed was the installation of TrueStormsF04.esp through NMM, but previously I'd been playing around with FO4 mods before NMM updated to include F; I might have messed something up somewhere accidentally. Are there diagnostic tools available for this scenario? Thanks! :)
