hmm, it might be possible for me to have completely missed the renfield quest, but after checking my journal for quests and finished quests i have not discoved anything which would say so. I have spoken once with this Xzar, which had a very pointless quest for me if i remember since i am a paladin, i turned him down (probably the wrong thing to do) . I do remember my previous game the jaheria stuff went along just fine, but this time it is rather buggy. I havent even gotten into any of jaheiras quests besides her poisoning, which is very odd, i think its a bug. I have tried using shadowkeeper to import renfields body to gain access to the harper hold by presenting it to the door guard, but no new dialogue options show up, but i will keep trying. It is very possible that jeheira could have gotten petrified, with my luck that is very possible. I am unfimiliar with shadowkeeper though, it seems useful to check out items i dont have and want to aquire though
I have Shadowkeeper 1.4 BTW. Thanks for the replies, it has already helped immensely!
