So this started happening a couple days ago. It's an odd issue. I've updated Nexus and everything. It also happens to mods that are also not installed via the Nexus. One, it doesn't do a mod limit anymore. It's been running fine up to this point. I loaded a save, and everything modded was unequipped, and my settlement objects were gone. Everything. The mods had loaded up, seemed like they were there, BUT they also seemed to go through the in-game reinstall process (Like Snap-n-Build had the pop-up saying it successfully installed despite it had not been reinstalled). The DLC had popped up with the quests as if they were reinstalled. My character had lost her hair, equipment, everything, although I could still respawn it via the console commands and re-equip it. I figured I just had a corrupted save and just made a new game. The new game worked fine... until I started it up again. Same issue. I've looked everywhere and it doesn't seem like this issue had been brought up in other forums, and I had updated the Nexus, restarted Steam, reinstalled F4SE, and I hate for my last resort to be to reinstall the game and reactivate all my mods... especially when it isn't guaranteed to fix the issue.
