So i have the eye of the falmer to give to delvin and the topic wont come up where it says that he will buy it from it and it is really pissing me off... i have reloaded an earlier save and restarted my xbox... does anyone know what i need to do here/ how to fix this annoying little glitch please help

Let's see, there's two eyes of the falmer. He only seems to take the left eye, the right eye can just be sold to a vendor or something.
