I'm doing the Power to Quit Anything power pack and picked that I wanted to do replacement, deleting the other two types of quitting. Then I realized that the phrasing of the replacement quests didn't work for me, so I restored the Make Your Decision quest and retook it--but it didn't re-generate the other quests. Now I have to restart the Power Pack entirely, which is really annoying. Restoring and redoing a quest should delete and re-generate subsequent quests.
