Any Bonus Objective that has an alternative variant is currently bugged. That is, if the achievement for the zone (Such as Talador or Gorgrond) has a criteria which is “Objective A or Objective B” neither one works.
The required criteria for these events to trigger is to have your outpost in a given zone be constructed, and which objective you can then complete is decided. In Talador, for example, you can do the Zangarra objective if you built an Artillery Tower, OR Kuuro’s Claim if you built an Arcane Sanctum instead.
I have checked areas for all these objectives with one outpost built, and all of them AGAIN after paying the 5k and doing the quests over to construct the alternative building at the outpost, and still, none of them work.
So to clarify; with the Arcane Sanctum built, I checked both Kuuro’s Claim and Zangaara, and neither one was available. After paying the fee and doing the quests to complete the construction of the Artillery Tower, I went back AGAIN, and still, neither one was available. This was also true in Gorgrond.
This means that the achievements “I Want More Talador” and “Make It a Bonus” are completely unobtainable right now.
