cache not saving when using gradient ramp

[ldotchopz]

I have the gradient ramp used in a scale operator and for some reason it makes tyflow constantly update the cache forward and back. if i update to a jpg of a gradient it works normally but i like the built in one.

have recreated it in a simple scene where it's not so noticable, but in the scene i encountered it i becomes unworkable.

hope i'm just wrong and it's not a bug.

Cheers!
