Hello I think i found a bug... When i am about level 45, the Darkness element disapear, i can't chose it ??! so i chose an another element, and then darkness is back... i tried with 4.2 and 4.2d version... i play always in short mode.. here are my elements chosen.. Interest > Interest > Interest > Light > Fire > Earth > Light level 2 > Fire level 2 > Earth level 2 (and then, impossible to chose darkness...) i can't build periodic with that bug ^^ thanks
