H1Z1 KOTK Crates? Why were they removed from being sold on OPSkins, and will they come back?

So, many of you know, a lot of h1z1 crates were going up in price, and then around the steam summer sale happened, opskins removed them from being sold. Now, I may be over reacting, but i'm gonna be really mad if opskins doesn't ever put that option back up (I was really looking forward to selling them on there, but can't anymore). The only reason I can see why they removed them was because everyone was selling them to get money for games on sale during summer sale, which messed up the prices, and opskins didn't want to lose any money. If anyone has any info on this topic please let me know. Thanks.
