I did a search for this, and somebody had posted this problem in the Uvirith's Legacy thread, but a solution was never forthcoming.

I'm getting a game breaking dialogue loop when I talk to the apprentice Gavyn after becoming a vampire via the elixir, and Gavyn is already a vampire. I read in the PES comments section that you can fix this by changing a journal variable or something like that within the CS. My problem is that I have no idea what I'm doing in the CS. Does anybody have an easier solution to fix this (like could a console command update the journal to after this conversation and probably skip something, but still get me playing?), or could anybody give me some instructions/tips on how to fix it in the CS? I would greatly appreciate it.

Thanks.

I already PM'ed this to you, but I'm going to post it here to give other people having the same problem a quick reference

--Open up UL in the Construction Set (check the "active file" box next to it after clicking the "open" button)

--In the "Characters" menu, click dialogue

--Go the the "Greetings" tab, and filter (using the selection box in the lower left corner) for "apprentice gavyn"

--Click Greetings 1.

If you look under the "Greetings 1" tab for Gavyn, there are two dialogue responses beginning with "now that we are bound by blood master/mistress...."

Under Function Variable for each of those responses, you SHOULD see the following
Journal HT_VampApprentice = 50
Function Choice = 97

For the one for "mistress" you should also see
Function PC six = 1.

Under the "Results" box for EACH of those responses should be the following
Journal HT_VampApprentice 60
AddTopic "vampire"

Then save the mod. The bug should be fixed (at least that's how I did it in my game)
