In several Europan Quests from Variks, he asks you to complete tasks while wearing a full set of Europan Crystocrene gear. For example Europan Gear II. Before Edge of Fate, these missions could be completed by applying the Crystocrene armor ornaments in lieu of using the actual article. [url=https://www.reddit.com/r/DestinyTheGame/comments/jsjmou/so_how_do_i_get_the_crystocrene_full_set/]See this thread on reddit for examples.[/url] Therefore, this is either a bug, or an undocumented change to disallow the completion of these missions using ornaments in lieu of the actual armor pieces. It could also be a flag that wasn't set properly - so, just a mistake. In any case, since the Crystocrene armor is functionally useless - not to mention, not part of the tier system - players have no reason to think they need to keep these armor pieces. Please revert this change, or fix this bug. Its not unreasonable to allow ornaments since previous ownership is a prerequisite to making the ornament anyway.
