I’ve just been informed that the malignancy range is back with macrocosm and will hopefully be released next week!
It's in the link provided above - Jason Lye, lives in Bethesda, Gwynedd. You don't need a FB account to visit the site or even to read public groups and pages, but you can't post or use the market without one.
Actually can’t access any details from that link other than asking me to sign in to a Facebook account, but I’ve made contact thru messenger, Jason has passed the range back onto macrocosm
