Frequency: Lasting even after relog
World name: Sargatanas
Character name: Rhea Kyokuna
NPC name: Delivery Moogle
Monster name: /
Class/Level: Monk / 50
Party or solo: Party size of 4
In-game time: Server Time 0:50
Area and coordinates: Every Delivery Moogle
Steps:
1. Was claiming items that were bound to a mail from a free company member
2. Duty Finder popped up with Amdapor Keep Dungeon
3. I withdrew since I couldn't claim the items from the mail with the duty finder pop-up open
4. Claimed the items and closed mail, queued up for Amdapor Keep again and finished the dungeon
5. Checked Delivery Moogle again because I apparently had a new mail, but it was the same one from before that I opened and claimed items from earlier.
6. Can't open any moogle mail ever since

The issue seems to have resolved itself after 12 hours +, but it's still weird and needs to be looked into
