I am having the same issue. It would be great to hear if there is attention being paid to fixing this via a patch. I would prefer not to roll back my version... plus my save is a multiplayer game and I don't want to bother my friend with having to roll back his version either.
Any info would be great.
A little more info: this only seems to happen with the saves that I have activated some of the previous perks on such as Pet Pal for my party, sourcerous sundries and hagglers. I think those are the only perks activated.
When I load saves where I haven't activated any perks I have no problems.
Thanks!
