Toon Lit Shaders not working properly in UNity 5

The Ramp in the shaders started acting weird in unity 5... Before asking this question i analyzed what could be causing the issue... And from what i've noticed... the ramp is sort of applying singularly to the various texture clusters (For example: i have some fields in the main terrain (which is a polygon, not unitys built-in terrain), these fields have a different texture since they're not plain grass... and are square separated square texture clusters, and for each of these the ramp acts independently giving a horrible discontinuous effect)... Not only this...the whole thing is weird... there are huge spotlight effects giving that plastic kind of look. I tried looking at the scene's light... but it seems fine... Anyone having this problem?
