I'm trying to take things back to my house in Falkreath, but I'm over the weight limit for my character, so all I can do is walk.
I went to the boat and asked him to take me back to Skyrim. He takes my gold and the screen goes black and gives me a loading screen.

I'm still in Solstheim.



I tried it again with less stuff and I'm still svck in Solstheim.

Do I seriously have to take my stuff back in 6 or 7 trips back to Falkreath because the stupid boat is glitched?

Have you tried the fast travel option?

Save, quit, restart your Xbox, come back on and hopefully the game will have fixed itself. Otherwise, just sell some stuff and fast travel.
