Normally you can't track quests that have "no objectives", there should be an option to make them trackable. The objective listed in the tracker can just be the top part of the quest text.

It would indeed be nice to be able to track quests without objectives since the classic UI would tell you that you can't

When you try to track it manually with AutoQuestWatch_Insert() / AddQuestWatch() it will count as being tracked but nothing will actually show up. I don't really know how to solve this problem with minimal effort
