Okay, here's the deal: I've gotten to the point in the game where you fight your first Dragon at the Western Watchtower, and after playing for a few minutes after Irileth shows up, the game just crashes for no apparent reason. The Papyrus Log mentions "DLC2", and that's about it. If I turn off any of the DLC, it won't even make it to the Title Screen without a CTD. Anyone know what this is about? If you need more information, just ask.

You've got a mod acting up that depends on that file (DLC2, whatever that is) as a master.

Well, in that case, here's the last line of the Log File:
