On Mangler, we have two guild members that have completed the "Underfoot Veteran" achievement via raids. They both have the achievement for "Unlock the Mystery (Raid)" checked, and were with us for the three required raids: The Fungal Corruption, A Cunning Plan, and An Audience with Brell Serilis. However, they do not have access to zone into Volska's Husk (and therefore can't zone into open-world Convorteum). Both have also completed the Underfoot Adept achievement. The only thing they are missing on the raid side is "Trial of Creation" in Brell's Temple. However, per the achievements this shouldn't be required for open-world access. Unless this is bugged for another reason, I'm guessing Trial of Creation and Trial of Deconstruction may actually be required for open-world access, and if so the achievements are wrong. Please let me know if we are missing something.
Here are screenshots of the achievements for these members. Underfoot Veteran states it grants access to T3, but they still can't zone into Volska's Husk or Convorteum.
