So I just beat the "Lost to the Ages" questline and during the final part of the quest (in the actual forge) I get massive stuttering/sound loss. It starts off when the Dwarven Spiders first start to attack you, and actually continues on until the Forgemaster makes his appearance. Everything seems to go great up until that part of the quest. Has anyone else had this issue?

Played fine for me the first time, that was before Hearthfire was installed though, the second character has not done it yet.
