Looks like more of a gui error or such. I'm sure, as Voldex hasn't given us any info.

I think this is intentional tbh. Because you can't get purple collects in boss raids (unless they're god pot), they probably added this.

Yeah, I've been seeing a lot of people drop legendary boss raid armors. I'm pretty sure they'll be worth an old leg soon (once more information is given)

What should I give this guy for it? He said he can trade it if I give him good offer
