Realtime lighting is different after I build and run

I've been working on my game for quite some time, and when I run it in unity everything works well and looks good, but after hitting run and build, the real time lighting gets glitchy. Certain objects in my scenes(which in unity would light fine), remain unlit when I point my flashlight at them, other objects do get lit, but when any part is lit by the flashlight the entire object lights up(not just the part the spotlight is 'touching'. all of the scenes have had their lightmaps baked and I don't know how to fix this, Any ideas?
