Dont know if this will point out anything to further help you out?
I was looking up Freshly Picked Vana'diel 8 and I came across this topic section of the page and wondering if this helps you out in anyway? Look down into the thread about the restrictions they had to implement for a temporary measure over hidden bug they've found.
On A Side Note: Glad to see these two threads coincide with each other: here!
I found an issue with calling forth trusts's in few area's i'm bringing to attention!
So i was looking for the survival guide in Toraimarai Canal entering from windy walls but I found out I wasnt able to call trust npc's inside with the message cant call this npc in the area at this time. Telacove I had the same ordeal stating that I cant call em forth in that area as I tried to do it before entering the battlefield called give my compliments to the chief with an oboro fish nm inside on a level 81'ish thf/dnc40's. I hope with the elbow grease there giving trusts it fixes this issue as well.
well found out trusts are still unusable in some older level synced quests! -.-
I was going to knock out some really old quests that cant be removed unless there completed but the older quests like echo-warrior there is no point in getting people together for it since the rewards are so miniscule and so only be allowed to solo something like that with a level restriction to it of about 20 and so I went to test out if I could use trust's to complete a task that no one is going to come together to do except your trust's and yourself. My trudt suggestion, hmm well i suppose time to jump to the appropiate thread for it: http://forum.square-enix.com/ffxi/threads/38859-Trust-Suggestions!
