How do I get rid of a miscellaneous quest objective in the journal without using setstage?
Looking for a solution, I stumbled upon a mod that could help you out, called Quest Eraser, by user kryptopyr:
This mod will remove various quest objectives from your journal.
When activated, certain quest objectives will be removed from your journal. You are given the option to remove all of the qualifying quest objectives or to remove only some of them.
