I seen this bug on a few items. It was also on a core element I placed into my league bank. I removed the stack so it was 1 and 15. Then deleted it. You cannot use it for crafting if it has that written on it. It's the same protection that you see on items.
Well, I hope the deletion of a few items wasn't a mistake. It was an Oly Core which is easy to get off the broker. I don't have any of the ranks in my inventory but see it when adding things to the league bank.
I really hope not, but you know, they have that "we don't put new things if we aren't going to get money from it" politics
I guess the 0 Combat Rating items might be free to use for all CRs, I don't think it is bugged or something like that!
Oh right. As I know we can use broker even in the Police Station when we are level 4. So that kind of items might be useable for everyone. Or something very special. Or maybe that just looks 0 in the broker, might be changed after shopping.
