yep, turns out im just stupid :D i used my aura forma and wondered why i couldnt choose a new polarity lol ty
So i bought an umbra forma frome teshin and put it on mesa. It would be the second one on her. But when i used the forma it didn't got me to the mod slot selection window for the forma but to the mod window instead... now 150 SE are gone and the forma and my mesa is r0, too. It feels like beeing punished for playing that game... is that a know bug? does anyone know where i can get help with that?
