The Feat for the Lava Material available from Teen Titan Vendor in Watchtower doesn't register upon collecting the material to use. I have contacted Danny at Daybreak & he tried to fix it yet wasn't able to so please someone from the Dev Team fix this slight issue at their earliest convenience. Thank You!
Just to be sure you cover all possibilities, by chance did you collect any other material from TT vendor? Because there is one feat for any material, not one for each.
The Feat for collecting said material is called ''You're Villain Material'' of which did not show up upon collecting it.
What I mean is that you can get the feat for collecting the Lava mat, but also you can get it by collecting Magma mat, Ikon mat or Critical Ikon mat. Are you sure you did not get the feat in the past by collecting one of these other materials?
