Some cards which are missing horizontal lines on the main site:
Great Hall (+1 card, +1 action should also come before 1 VP)
Nobles (text should come before 2 VP again)
Dame Josephine (text should come before 2 VP)
(I don't own promos so I can't check but I would guess Black Market and Stash have lines.)
*The printed version of Harem does not have a line, but DXV acknowledges that it should...I don't know how you want to treat that case.
A few other very minor differences I caught (I didn't check all cards. I don't think any of these change how the card plays, but you never know.):
Apothecary should say "...back on top of your deck in any order."
Scrying Pool should say "...that is not an Action..." ("is not" instead of "isn't")
Golem should say "...Golem cards..." (lowercase "c" in "cards")
Possession has a line break between the two sentences.
Spoils should say "...to the Spoils pile."
Vagrant should say "...Curse, Ruins, Shelter, or Victory card..." (different order)
Hermit should say "...You may trash a card from your discard pile or hand that is not a Treasure..."
Armory should say "...up to $4, putting it on top of your deck." (all one sentence)
Ironmonger should say "...Either way, if it is an......" (adding "Either way", and also there is a "..." after "an")
Rats should say "...When you trash this, +1 card." (not "when this is trashed")
Band of Misfits has a line break between the two sentences.
Count has "or" between the first and second options each time as well as the second and third (that is, "a; or b; or c")
Hunting Grounds should say "...When you trash this..."
