You fixed the ability to preview offhand Guardian Fighter (all classes??) so that we can now see what the offhand will look like before purchase. But, now there is an even worse problem. If you want actually to change the offhand to what you purchased, the offhand does not show up in the change appearance menu. I tried both the Adamantine Scutum and the Blackiron Kite Shield, both BoE and BtC, before and after login. I can preview them, but I cannot use them as an appearance change. I also tested an offhand shield that would drop from a mob (some generic +6 shield). It showed up immediately under options to change appearance.
