on killing the process and moving to that hidden vault again, it created a different vault correctly, BTW - so my game isn't lost.

Are you in High Peak?

[sound F/X: source diving] Hmm, what version of ZOmnibus are you using? That line number is a bit off from what I've got.

At any rate, my preliminary assessment is that this probably isn't a ZOmnibus bug; the bit that shows in the stack trace is just the pass-through from Store Wish List where we suppress its popup while transmo'ing stuff on level change, and it looks like I'm passing all the necessary parameters through to the base module method.

I was in High Peak, correct.

I see 'ZOmnibus Addon Pack 17.1.2'.

other addons installed Barbarian Class Fork, Mountain Troll Race 1.0.0 (and local changes), Improved Auto-explore and Rest 3.5.0, Select your Escorts 2.3.1, Barbarian Evolution for Berserker 1.0.2, Playable Naloren Race 1.0.2

Since you were in HP, this is a basegame bug as it can be replicated without any addons and seems to stem from HP not generating artifacts (on enemies?) thus causing Poltergeists, which wield themselves, to fail to generate.
