I've just re-hired Lydia to have some adventures together for the old times' sake... and of couse to use her as my trusty pack mule.

To my surprise, when I picked "I need to trade some things with you", she replied something like "I am at your command". I exchanged stuff with her a few times and she NEVER said "I am sworn to carry your burdens". Before that, I had been adventuring with Jordis and she also never mentioned this line... Is it just me, or did they remove it from the game????

she usually says it when you ask her what a Housecarl does.
