I've had my fiddle leaf fig for about eight months now, and I'm still trying to figure out its moods

I've had my fiddle leaf fig for about eight months now, and I'm still trying to figure out its moods. It dropped a leaf last week for no reason I could see—same light, same water schedule—and I panicked. Then I read that they're just sensitive to change, which made me feel a bit better. Has anyone else dealt with this? I'm wondering if I should move it or just leave it be. It's my biggest plant so I'd hate to mess it up now that it's finally looking happy.
