Another potentially amusing, potentially cool story from yours truly.
As we all know, Gray's document (which you're not allowed to say in-game) is frustrating to get; some purchase theirs. I didn't actually know I could purchase them, but I wanted to try anyways, so I CC'ed and kept whacking boxes, until Miraculously! I found one. But... Uh Oh! Full inventory! "You cannot get anymore items." After complaining vigorously to my friends, I dropped three sapphire ores to grab the document. I mused to myself, standing sadly by the dropped treasure, and wondered if I'd be able to complete the quest and make it back before the items were taken or disappeared.
So, I scrolled back to town, spoke with General Maestro, completed the quest, initiated the new one, and headed back to Kulan Field 2, where I'd left the precious ores. I teleported across Off-Limits, refilled my MP, and teleported across Kulan 1. Finally, I arrived back where I'd left them and Lo! There they were! I picked them up and exulted to my buddy channel. ^.^
