I have noticed a lot of times, that when I get a material, sometimes this material appears higher in the screen (You know, when you get a material and this appears above your head). One friend of mine told me to inmediatly go to haven and craft an item with that material, and that it had better chance of getting UVs.
Is it true, or theres something else? Or is it just a bug?
Your friend just trolled you, hard.
