I've completed the questline, saved the game, and logged for the evening last night. Now when logging in this morning, Arkemyr and his constructs are hostile and i cannot get out of the lab area without repeatedly being killed.
Secondly, when reloading to an earlier save prior to completion to attempt to "re-complete", it has me fight the lava ooze and elementals, which also activates the contructs when hit. After downing them, it keeps me in combat indefinitely.
Please advise as I have wasted 4 hours trying to resolve this myself.
