Those issues are caused by a corrupt savegame. The patch doesn't fix the savegames. However, we can put back those characters if you send a savegame to support@larian.com detailing which characters you're missing.
I understand that the patch won't fix existing savegames, & I have sent mine in to you to be fixed. My questions are:
1. Should I install the patch to prevent additional problems or will it mess up the existing save game? So far I've only had the problem with Raze (didn't have it with Isabelle), but have not yet reached the other NPCs that are apparently affected.
2. I also see that there is a patch for FOV ... will installing the FOV patch prevent me from using my final savegame from DKS?
I'm also curious ... if the problem is a corrupt savegame rather than a bug, how is it that the patch prevents it from happening?
