Welcome to Everyone's Favorite Part of Skyrim: Troubleshooting Mod Issues
A new Skyrim means new upgrades – we've got fishing, all sorts of new gear, new quests, and as you might expect, some software tweaks. It's nothing too extensive, just a little something special to speed up a few processes. If you go for it without mods, you shouldn't have too many problems. But you won't, will you? This is Skyrim, after all.
It turns out that a few mods relied on Bethesda's upgraded processes. Now they are too fast and some of these mods are not designed to handle that kind of speed. The end result is a black screen – the music is still playing, but none of the usual tricks are able to get things back to a playable state. You are stuck and need to restart.
A prominent mod author posted a post on reddit warning people of the problem and described the technical side of things - at least as far as his own mod follower 'Lucien' is concerned: "I realized that this what was happening was that the script was running faster than it was. This meant that when the player loaded the game, Inigo's esp [for reference: Inigo is another follower mod that Lucien can interact with] was detected, so the game tried to grab his reference to put it in the a.k.a. However, since the script was running so fast, Inigo's reference didn't have time to load, so the script attempted to fill the alias with a NULL, causing a crash.
The solution this modder offered was to add a delay to this process, giving the game time to catch up to its own speed before loading everything.
If you experience crashes like this, PCGamer recommends avoiding all script-heavy mods – at least until their respective authors acknowledge the problem and issue a fix. The fix described seems relatively simple, so if the mod author is still active, it shouldn't take too long before everything is up and running until then. But in the meantime, take it slow and steady - I know the urge to mod Skyrim until it breaks is tempting, but you don't want destruction to be that easy, do you? not ? Give it some time and read mod descriptions carefully.
