Erik the Slayer has dissapeared on me. I released him from service over a week ago, and he has not returned to Rorikstead. When I resurrect him or placeatme his refid 000350b8, he appears as just Erik.
And his dialogue is what he says before you do his quest.

Here is what I have tried so far:

prid 000350b8
enable
resurrect 1

and also

player.placeatme 000350b8

He spawns, walks right over to the field, and begins farming.

Are there any other console commands or anything else to bring him back?

prid 000350b8
moveto.player
kill
resurrect
disable
enable

This should make it work.

I released Stenvar in order to do a companions quest after it was over I went to Windhelm to rehire him but he wasn't there. Then some considerable game time later possibly weeks I bumped into him outside of Whiterun fighting a dragon and rehired him.

After the 2nd console command, I get the following:

Syntax Error

Unreferenced object

Unable to compile script

Sorry.

It's 'moveto player'

No problem. Tried those commands and Erik appears, but not Erik The Slayer. When I click on him, he just keeps repeating "You look like you...." which is what he says to begin his quest.

According to uesp 000350b8 is for Erik The Slayer. So why does this npc resurrect as just Erik?

What else can I try?

try 'setstage RoriksteadFreeform 30' after you resurrect him.

Thanks for your help.

I checked roriksteadfreeform with getstage and it was at 30

I set it to 20 and got Return to Erik. Was able to select dialogue with him, and chose to finish his quest. He walked outside, went back to farming, and now is now back to repeating the dialogue of beginning his quest. Without allowing me to actually select any dialogue from him.

Found him!!!!!!!!!!!!!!!!

He was standing outside Nightcaller Temple. In the cold, with his sleeveless iron armor. Did a savegame. Let Cosnach go. Clicked on Erik The Slayer. And hired him for 500 gold, just like we were in his dad's inn.

Man, he must have freezing standing for a week
