[QUESTION] G string keeps going REALLY out of tune and idk why

I have a floyd rose special with locks at the nut as well. For some reason, when I use the whammy bar, the G string goes out of tune super super fast. None of the other strings do. I'm talking a half-step out of tune after just a couple whammy bar uses. I just replaced the saddles a few weeks ago and everything was working great until today for some reason. I didn't even change anything.
