Graphical bug with weapon models

[ChaosSlayer]

I discovered a sort fo graphical bug related to some of the weapon models.

Here what happens. I have 2 weapons:

one which uses weapon model #029 (skull on a stick which you can see Prist fo Discord with)

another is model #097 which looks liek runed gladius with a blue spark particle effect goign over it (used to be a gm item on life)

here what happens.
If my 097 is equaped when i log in or zone all is good.
If i try to re-equpe it - its becomes invisable - ist simply not shown on my char (i mean the model)

trying to equp some other item after that (such as 029) will also cuase it to be invisable.

if I zone with either 029 or 097 equped- they will reappear.
If i try to swap or move them in anyway they disappear again.

Most of the weapon however show up fine even when these 2 go invis.
