Changing Intensity of Moveable SpotLight in iOS crashes ?

So my project is targeted for Mobile platforms Android, iOS.

I have a SpotLight set to Moveable in my level.

During the gameplay, I change the intensity of SpotLight from 0.0 cd to 1000 c.d.
On IOS the game immediately crashes, but on Android it works fine.

Is this expected behaviour? How can I fix this?
