I am also getting the same error with Mastercard in the webshop. What is weird is i can depo in the game with the same card fine, just cant buy any keys.
I think since there is no gravity in space the anti-grav part of those boxes shouldn't work. However just because there is no weight doesnt mean they have no mass, which is really what the equus limitation should be.
looks to me like the item info of the official tp chip was pasted onto the box with his gear. many people have item links of that stuff. i have links of most of what the ark dev team uses, doesnt mean I have it or have ever used it.
