Maya to Unity Scale Factor Issues

Hi,

I'm trying to export a model in Maya that is set to metres, has a scale of 1:1:1, and has no history. http://i.imgur.com/NNaUQCG.jpg

When I export the FBX and then import it into Unity, I change the scale factor to 1 (In Unity)(from 0.01) as always. http://i.imgur.com/ejpjFo1.jpg

In the last day everything seems to be breaking. I'll import a perfect FBX into unity, change the scale Factor to 1, but when I drag the model into the scene, the actual scale of the object is set to x0.01-y0.01-z0.01. http://i.imgur.com/534Kyeh.jpg

If i change the scale to 1, the model becomes 100x too big. Before I was not having this problem, everything would be 1:1 scale... I've tried downgrading to Maya 2012 from 2013, remaking fresh models, EVERYTHING, 4 hours of troubleshooting and I can't figure it out.

Any help/solutions/advice/input/whatever is GREATLY appreciated! Thank you.
