Umh wdf? look lol
 

just did this: http://youtube.com/watch?v=wEjxJ3c5w9Y
just wear a spotted cape, unwear and it is a completely diffrent item wdf?

dude wtf? is there any thing different about the capes like price high alch or anything?

It's just a bug with stacking, Jagex is aware of it.

the other cape is untradeble, if you log out and in they are the same items again, very weird

Ya. Once I had two gold piles in my bank. o.0

And that my friends is also how you get more -KG

Nice bug. I'm sure Jagex would be aware of this by now though.

its a bug, to get -kg

they fixed it, but it was fun to see -129kq. which i think led to smoke's inf run glitch

thats kinda weird..
