Clicked Pass on loot but it rolled Greed instead

[Mikio_Azuloq]

Time: July 15th, Tuesday, Around 8:00 a.m. CST
Frequency: Once (did not reproduce)
World name: Excalibur
Character name: Mikio Azuloq
NPC name: n/a
Monster name: Scylla (Edit: Glasya Labolas was the boss that was defeated when the error occured)
Class/Level: Scholar/Level 50
Party or solo: Full Alliance of 24
In-game time: no idea
Area and coordinates: Syrcus Tower

Steps:
1. Party defeated Glasya Labolas and continued to proceed on with the raid normally.
2. "Amon's Sleeves" item offered for Alliance B (the group I was in) and I hit Pass on the item.
3. I look to the chat and see that it says I rolled Greed on the item when I hit Pass.
4. I warn my party members not to pass the item yet so I can log out so I don't receive the item.
5. The combination of the logout being too slow and not all of my party members seeing my warning led me to receiving the item that I hit Pass for and causing me to wait 7 more days before attempting to receive the item I was doing Sycrus Tower for.
