Was playing with a friend today and attempted to use the skin (hadnt played as cravers yet) and realised its not even there for me. I do however have the messari skin there and working for UE so its not that skins just arent showing up at all for me, and i have the pathfinder hero skins working aswell.

Currently The Craver prime skin is only available for those that pre-ordered ES2 (This may change in the future)

I did preorder ES2, i just hadnt played them so i didnt realise the skin wasnt there. ill take a look see if im mistaken but im pretty sure

I assumed you did not preodrer as you lack the badge for it, although it is limited to those that pre-ordered the digital deluxe edition (The Craver Skin is the same) So if you probably pre-ordered the standard edition, don’t worry I would expect the content to be made publicly available at some point later on.

Ye seems i grabbed the wrong edition when i bought the game, ah well i'll live. Just have to wait for a grey or black themed workshop skin or make one myself :P
