Does it also apply dyes to your weapons?

Changing anything with the weapons will cause your character to unsheathe them, but you can have them put them back by pressing the 'sheathe/unsheathe' key, which I think is Z by default (I changed mine, but I think that's the default). It shouldn't be mapped to anything else on the outfit screen though, so it'll just have you put everything away.

It does make it irritating if you've got enchantments on the weapons and are trying to dye them, since every time you have to put them back to see how the blades look, but that's just how it works.

The guild trader thing is probably people spamming healing/buff/etc abilities in cities, it unsheathes your weapons no matter what you're doing afaik. And the dyes thing above is correct, perhaps you had an undyeable weapon before and recently switched?

It always unsheathes my weapons. Since I’m on PC, i just press Z to sheathe them again. (Z may not have been the default keybind. Idk.) it’s annoying, but while using the dye station, you’re probably not using your left hand for anything else.
So just hit Z when you need to. Gets rid of the ugly glow on your weapons so you can actually see the dye, too.

Completely alone, I've found I can change a shield dye a couple times and I won't draw it. But eventually any change to the shield dye makes me draw it forever after. Unless I leave the station and come back.

I noticed when changing around the colors on the Stonekeeper shield while it's not glowing.

Either it's specific colors that behave differently, or some kind of lag or delay that allowed the first few color changes not to 'register' and force me to draw it.

That came with update 30. The character's rotation gets reset when previewing any Outfit piece.
