I sent her home from Riverrun and a few hours later I returned home only to find she's not there. Maybe she got stuck somewhere?

Will she be "teleported" there after some time or is she gone for good?

Even tho Lydia was a nice companion I'm more worried about a nice set of dwarven armor I gave her.

Women...hmpf :swear:

She walks there. So she won't be there for like.. idk depends on where you ditched her. Could take up to 3 in game days. Took my wife a while to get her ass from Whiterun to Solitude.

true that, i somehow lost my lydia outside whiterun... (i got on my horse and whizzed off). She turned up 3 days later at Windhelm when i went to see Ulfric the Goat.
