[1.0.50] Recurring Bug at Black Desert City Scraphouse: Shopkeeper is replaced, but not interactive

[spacefiddle]

I've had this happen several times now where the Scraphouse shop just breaks. Doing an Import restores functionality.

Quin, the actual shopkeeper, is nowhere to be found. (All Soldierbots and Security Spiders are accounted for, so I do not believe there was any normal combat.) The weird part is: Dack is standing in the exact spot that Quin always stands in, and his status shows "Goal: Shopkeeper." Except you cannot talk to him, as always.

In both cases, I witnessed the scripted exchange between Quin and Dack where Quin threatens to get rid of all Dack's stuff, on my first visit to the Scraphouse in the playthrough. So I'm not sure if this was meant to happen and Dack should now really be the shopkeeper, implying that he got rid of Quin for threatening to throw out all his junk, which would be pretty funny... but either way, several times now, on my second visit to the Scraphouse, it's broken with no usable shopkeeper - just a silent and immobile Dack with no interaction option, standing in Quin's spot instead of wandering around.
