so i was updating my prefabs, referencing all the objects accordingly but then my game stopped working, and its only working in 1 out of 3 scenes i have now. i have no idea what just happened on my non-working scenes i have null reference errors although they have references to them like they had before and the game ran fine. Once i updated my prefabs the game simply stopped to work. Now i can't even make my prefabs work at all, i tried to create a new scene and nothing works correctly scripts not doing anything, materials not being assigned correctly. all thats working are the collisions. did i broke my game? do i have to do everything from scratch again?
