The first is that Kettigrim will just say "I told you everything you need to know" when Vendel goes upstairs to meet with Balvene, despite the fact that he hasn't actually said anything of note. No slips of the tongue were made, nor was any Sujamma requested. I had to run "set controlQ to 0" on him to progress.

The second is more of a suggestion; as I leave the manor and begin to walk toward's Arvud's exit after all of this, I am immeditaly asked by a guard to see Balvene (who has lost her gems). Perhaps this should be delayed a bit?
