Found a rather strange error. Every time I approached Bruca's Leap Redoubt my game would CTD. I deactivated my entire modlist, started a new save file, reload a few mods, restart the game and approached the place again. Rinse and repeat, as soon as I activated Beastess, it crashed again. I deactivated the Forsworn Beastesses, but it still crashed. With no other mods active spawning enemies (thought those Forsworn Beastesses to be the fault), I'm not sure what could cause this.
Hope someone else can test this too, figuring out if this is a mod conflict or a problem with Sexlab Beastess it
