Defeated the 3 druids, defeated the final boss demon (even got the victory voice line, “You’ll never harm another soul…” and then… the stronghold reappeared after about 5 minutes, as if I never defeated it. The environment no longer glows fiery red like it did before defeating the boss, it remains ‘cooled off’ since I beat it, but upon searching for the unlocked waypoint, the quest dialogue began to repeat itself, (“This place is a ruin, what happened here?”) The waypoint remains locked and the red stronghold symbol has returned to the map. Did I miss something? Needless to say, extremely frustrating as this was not an easy battle, and one I’d rather not do again.
There is usually a bell to ring, or a thing you need to click in order to complete the stronghold. Did you do something like that, or get a message saying you need to light a beacon or something?
You might look for a YouTube video showing the last step you need to do in order to complete it.
Ugh, would that really restart the Stronghold if I leave the area without doing so? Damn. Thank you for the tip.
