Uhm... what exactly is this?

I just bought the gladiator gradient and the gladiator blood from a user shop.
They were in fact not broken(the first of which I have seen that weren't) and were in my inventory to be activated.

All was fine until I actually tried to activate them. a message pops up saying

"remove 80047 from set"

Can anyone tell me what this is and how to fix it?
Thanks.

Edit: The link to the shop is http://forum.toribash.com/market_ite...gory=1&page=31

are these items in a set? if so, you should probably unpack them and try again.

Those items are currently in a set (that likely is not in your possession) according to the error message.

Problem should be solved. Please report here whether they work now or not.
