Steps:
1. I was fishing in my Mog garden pond last night using a Lu Shangs rod, Insect Ball, Seagull Ring and Albatross ring. I logged out after returning to my mog house.

2. This morning I logged in, and exited the mog house to Western Adoulin (H-11). I then "examined" myself and noticed that not only was there an Albatross ring in the Ring Slot, but also one in my Neck Slot. This could only be seen by the "Examine" option, but was not present in the "Equipment" screen option view, nor could I select it.

3. I opened up "Equipment" and put a Warders Charm in the (what appeared to be) empty Neck slot, and then took it off. This fixed the issue and the Neck Slot was now empty via the "Examine" screen.

I don't know if this had any bearing effect, or if it was just a graphical glitch caused by zoning/zoning in. I use retail FFXI. I thought I would report this in case it DID have an effect, which I believe would be detrimental to the game.
