Steps: I submitted this bug previously here. It was initially moved to 'Accepted Bugs', then to 'Insufficient Information', though no specific additional information was requested.

After having reviewed the requirements to obtain these key items on multiple websites (here and here), and having verified my completed quest logs and key items on multiple occasions, I believe there is a bug preventing me from obtaining the Bronze Shovel Cordon and Silver Shovel Cordon key items. To confirm, I have verified the following:

• Obtained both Ivory Wing Talisman key items
• Completed all Adoulin quests through the final reward tier granted by Reja Ygridhi - received 30,000 bayld reward upon completion of my last Adoulin quest (Mistress of Ceremonies)
• Completed all Coalition assignments through 'Legend' rank (with the exception of the 5 'Provide' assignments no longer available from the Courier Coalition). I have 90 completed Coalition Assignments in my quest log

Thank you in advance for your assistance.

-- EDIT --
Since I'm unable to post to this thread, editing this post to provide an update.
Killing both Yumcax and Hurkan unlocked both the Bronze and Silver Shovel Cordons, so this issue has been resolved.
