Hey,

since I activated Heartfire the game crashes without an error message as soon as I remove the soulstone in nightcallers temple (vaerminas quest) to deactivate the door seal. I've been trying without any mods, as admin, with the unofficial skyrim/dawnguard patch. Still the game crashes.
This issues occures since this latest dlc for PC, before I did this quest several times without any issues.

Any Ideas?
