after 12 hour of playing, i can finally idle at area 2in SH3 XD little balancing migth be needed. Also relics will be cheaper, and that fist area bug is causes because you can die at first area --> game automaticly throws you to area 0 which doesnt exist!
The bug was causen by existles enemy at ice plateau, if you encountered it as first enemy, no gp and exp gain were set. Same thing is at arena which i accidently opened, do not save at arena, and then quit playing
