Okay no matter how I look at this; its still a bug...

if you look here you'll see a armor merchant selling monk armor that needs what looks like Silk to me. But when hovering over it it says requires Linen.

and here you'll see what silk looks like in my inventory

and here is what Linen is supposed to look like...I say it is messed up!

Yeah, yeah it is.

So long as it still accepts what it SAYS you need though you're alright 'eh? Worth noting though I suppose.

lol, I've never had silk so I couldn't reference it. But you are right, they need to switch that graphic.

Do a /bug in game or email them. Not sure they would visit the screenshot area to see this bug.

this is just one crafter...in Kryta perhaps...? I'd be able to give a specific location(maybe) but I don't know how def on Monk's crafter items works...so it's just an assumption from the background. Anyways, if this is just one crafter, in the middle of the game...why even bring attention to it? You should know by the time you reach Kryta which materials you need for your different sets of armors...

Why not? It is a quick bug/graphic change. It can be put on the bottom of the list, but there's no reason to just leave it wrong.
