After using the command Ressurect 1 after Ghorbash had died in battle, he stopped following me and I can't get him to follow me again. He's acting like he did before I convinced him to follow me in the first place. is there anything I can do, or am I going to have to find another good follower?
When this happens to me, it's because for some weird reason, the follower's relationship to the player character has decreased. Most followers will only follow you if you are at a certain positive level of relationship with them.
If playing on the PC, to increase your relationship level to Ghorbash, you can use the following console commands:
That should set Ghorbash's relationship to you as 'ally'. You can also change the '3' in the console command to '4', if you want to set Ghorbash as a 'lover'. That will also allow you to marry him.
The conversation option to ask him to follow you again should now appear.
