I started the game with a different starting mod, didn't like it and uninstalled it thinking my game would start from the quest going to Riverwood.
Well... It didn't. My character is lvl 41 and 60k+ gold! Don't really wanna lose him.
So is their a console command to boot up that quest?

Wait a min...You installed an alternate start mod, played to level 41 and uninstalled the start mod?
And now you want to continue a level 41 character from Helgen?

How is that supposed to work? And you expected that to work?

If your character is already a level 41, I think it's already too late to be thinking about that.

If it's the mod I'm thinking of. And you just want to start the main quest. You can do that at any time, by reading the Adventurer's Journal found on the Burnt Corpse just down the trail from the cave exit.

This was implemented by the mod author to start the MQ at any time no matter what alternate start you chose or how far along in the other quests you are.

K, I'll try that.
