So I wasn't sure where to put this, but it seems these things are usually mod-related.

For some reason, I can no longer trade with Lucian in Riverwood, nor Belethor and Arcadia in Whiterun. However I can still trade with the girl blacksmith in Whiterun and Farengar.

The Golden Claw quest is active. When I try to talk to Lucian, no dialogue options even come up, he just says a one-liner and that's it. With Belethor and Arcadia, I can talk to them about all their other options except "What do you have for sale" does not appear.

I tried disabling then enabling them via the console, but that didn't work.

I can also trade with the other merchants who are outside in Whiterun, like the meat seller and such. Just Arcadia, Belethor and Lucian are the only ones who I can't trade with. This is a new game though and I haven't been to other locations to see if other merchants are the same way.

Only thing I can think of is that it has something to do with Belethor, Arcadia and Lucian being in interior spaces but the others (the ones I am able to trade with) are outside. Oh yeah, and I can't trade with Hulda in the inn, either. Any ideas?

Bump. Anyone else have this problem?

Seriously, am I the only person who has this problem?

Are you using Economics of Skyrim? I believe that mod has some problems.

I don't think so. My modlist is:

Mark and Recall
More Rain
Morokei Mask Magic Armor Tweak
Playable Greybeard Robe
Better Mage Related Rewards
Tytanis
Walk
Hvergelmir's Armor and Shield Retextures
Inhabital Shacks
Stronger Alduin
Weightless Unusual Gems
Unenchanted Thalmor Robes
Master and Expert Hoods
Faster Vanilla Horses
Enhanced Blood Textures
Reduced Distance NPC Greetings
Spend Dragon Souls for Perks
Unofficial Skyrim Patch
Bassem's Better Deadly Aim perk
Specialised Followers
Fur Hood HD
Water FX - Get Wet
Better Winterhold
Winterholdrebuild Project
Enhanced Dynamic Weather System
Deeper Snow


Not sure why any of those would influence those merchants?

Can you post your loadorder from plugins.txt in c:\users\(your pc name)\appdata\local\skyrim?

Forgot about the extra enchantments thing.

I'd backup your saves, and then uninstall mods one by one, and after every uninstall you test if you can use a merchant.
