I had this strange experience the other day, forgott to take a screenie unfortantly, but its easily enough explained. I play on useast closed sc ladder and was making a new sorc. As i ususaly do, i equiped her with siggons as soon as she had enough str to use it. Siggons gives a very particular look when put on and is normaly easily recognizable. However when I switched to my second computer, and had a look at the sorc, she was NOT wearing siggons, but appeared to be quite in the nude.
I also asked the person I was playing with if it looked like i was wearing siggons, she said that no, I did not.
The LCS was uppdated to reflect the siggons stats and when I went into combat, it was also clear that i was using it.
I could take it of and on again with no effect on my second computer, on my main computer it showed as it should however.
I guess its just a gfx bug tho, as it didnt seem to affect my play.
edit: i found the reason in another post here, its probably cause i was using +str charms to be able to wear it. (se the no armour post further down on the forum)
