North of Ked Bardu in Dry Steppes, Kotama Grasslands there is an Altar of Lilith that is located just inside the Dry Steppes zone but it does not count towards the Dry Steppes completion. Technically there are 34 Altars located in Dry Steppes but one of them doesn’t count towards the Dry Steppes completion.
This misplaced Altar causes many players to think that they have found all 33 Altars, missing the correct one nearby, and ultimately end up with 32/33.
