the thing with this bug is that when you are in a lobby waiting for other players to get ready you can go customize your heroes while waiting. Then if you go on a hero you dont have materials unlocked, start spamming the material that is locked until the game starts. then when you are in game you will have the material that you should not have. You can see that the warden is rep 20 and he has black material. i have a black iron material on a level 14 lawbringer.
When the match is over, you will still have the material on your hero, but if you click on the other material(lets say iron) and you wanna get the black iron again you need to do the whole process over again.
this is my first post on the forums so if the link dosent work, then am sorry
Thats about it
