I think i have bug were i can no longer get any UVs on my crafts,atleast for my brandish`s because before i used get a UV once every like 3+ crafts and now i have crafted like 15+ brandishes and i havent gotten a single uv.i also tried crafting a few firotech`s but i havent gotten any UVs on them either
UV from craft appear random and not always~ some people can get it when craft over 30+ and some people can get just by 2 craft
it's all depend on luck and this is not bug
