LIETHEPENGUIN'S PROFILE

I have an issue! I defeated the rift Dragon and got the origin gem. I Noticed that it was useable so I used it. It went through the little cutscene like thing and screen went white and it said something about an item matwrializing in my hand. Now my issue comes right after this it goes to a black screen and an error occurs " Script 'Wij_SceneTreasue' line 45: NoMethodError occured. Undefined method 'screen_x' for nil:NilClass
