I have never seen a vh asi magnus in the forums and stopped trying to craft/roll one after wasting 50$.
Who knows if it's even possible to get that UV? Imo it's very easy to program the game the way, certain UV's can't be crafted on specific items... Maybe it's just bad luck, but manipulating gambling machines is a common practice in real life too.
So being left in the believe there is something wrong I will never waste a single $ on punch again. But of course you can prove me otherwise and get your 40kce bounty.
UPDATE!!!
The Gun has been crafted. I will eventually release the name of the lucky person here if he wishes to be named!
bump for justice!
