NPC Rejold Barleybrew still doesn't offer 'The Perfect Stout'

I didn't realize that, thanks.

NPC Ragnar Thunderbrew doesn't offer it.

Also, NPC Rejold Barleybrew doesn't offer 'The Perfect Stout'

Any specific reason why's that so?

Cannot loot the item (Felix's Bucket of Bolts)

NPC (Volcor) is not respawning so I can't turn in quest. (Also this prevents me from starting the next one, which he offers, but that one seems to be listed on quest completer.)

Quest seems to be there and is not listed on bugged list, but I can't seem to accept it for some reason.
