Hijacking this a bit.
I’m on 0.65 and this part of the quest seems to be stuck for me as well.
I gave him the glue and he might have glued himself to the house because he’s never left….
Definitely been more than 3 days, I can’t seem to find him in any of the usual places. Maybe some flag got weirdly crossed because I gave him the glue while in the tavern at night?
UPDATE:
Nope, wasn’t that. I reloaded a previous save and did all of that during day time. This locked me both out of finishing the house as well as out of progressing the main quest as I cannot gather the signatures for both the drunkard (who’s missing entirely) as well as the barkeep
