If you add redundant vendors, then there's no visible consequence.
It's a fair trade off for a very difficult fight where if you took the high ground and don't defeat the demon quickly enough, or protect her mind, you permanently lose Lohse.
Simple fix, move the vendor somewhere you're bound to see them before the boss fight. I think it was said the vendor also drops skill books (And you can make some out of scrolls you find as well). Or name the Vendor as one of the recognized people, pending you've spoken to him. Some people rushing through things might still miss it, but that's on them. A third fix is just to add a couple of skill books. To be honest, you're -really- not missing out on any skill books at this point you couldn't acquisition on the nameless isle from memory, or make on your own even.
Anyway, I highly disagree with your choice of diction later on in this post, and it's rather arrogant and poor mannered to call people idiots if they disagree with you. You can be critical, but you would find that you would be more successful and taken more receptively if you did not insult the makers, and more importantly, fellow forum members.
