The line in his script that disabled him checked for the same journal stage as the one that enabled him, meaning he would be in the Infirmary the whole time, not just if he left the MG during the questline.
For the Dead Pilgrim quest, the Letter to Sadryn needs a small revision. I used "with all my heart" twice, and I feel this negatively impacts the readability of the letter. My solution was to simply remove "with all my heart" from the second instance, in the second to last sentence of the letter.
Replaces the Kartur roadsigns. Split into two ESPs.
TR_kartur_signs_fix replaces the wooden Kartur signs - most with Veranis signs, one with Omaynis sign, two with Kogotel signs and one I think I just removed outright.
TR_kartur_stonesign_fix replaces the Kartur stone sign with a Veranis stone sign (please review this with the latest T_Data, where a fix for the stone sign was merged)
De-deprecates T_De_Set_SignTownVerarchen_01, the Verarchen/Veranis stone sign, so it can be used to replace the Kartur stone sign in Roth Roryn (see the linked bug). The mesh is still in the BSA, so all this does is change the name of the activator and assigns it the correct mesh.
Corane Morianne said "this ancestral tomb" instead of "the ancestral tomb" in his greetings and had no AddTopic, meaning you can't get the quest topic, meaning you can't do this quest at all. Fixed that.
Hopefully fixed this quest so that it doesn't has a high chance of breaking completely. I do think it has other issues too (and could be simplified), but looping if you kill the guards was the critical one.
There was a disconnect between the information given by the questgiver, and what's actually written into the journal. I've followed the suggestion by Denis and changed both to reflect that he only knows they are somewhere near Arvud, and that you should ask the locals. He also marks Arvud on the map now.
