I was at Ruined Inn town. Kill all the siren and removed the monster den. But, the people do not return and abandon site does not clear.

is there a way to clear it?


Thank you

Have you cleared the cellar of the Ruined Inn? You'll need to use Aard on the debris to get to it.

Yes. I cleared it several times, Two specters are there. I killed them both but when I come back they show up again.

It's a known bug, nothing to do with spectres. Apparently this hasn't been and won't be (?) fixed, as CDPR isn't patching the game anymore.

Sadly the only solution is reloading a save before you cleared monsters' nest.

Zeff is right. Spectres not keeping it from flipping, the bugged siren nest is. Bugged. Killall console command does nothing, nor does that horn, which grounds sirens. Nor does dropping an altered trap, shoot down the inv nemesis... I just toggle my game to Easy, zip thru, and restart. The bosses in expansions are stupid hard, anyway, NG+, the vendors cash on hand drys up, when Scale Up is on. No real reason to have scale up, off. Soo. Food for thought, take care.

Old thread but finally I've got solution. I find it there:

Console command to make sure all sirens are dead:
