That is extremely weird... I've owned two FX's and I never saw a difference or change in behavior with which direction I had the spring in, and my first one had a muffed up spring!
I feel as if you should look into getting a new spring, or if your friend has an FX put their spring in your FX and see what happens. Because the spring worked the same on both my FX's and both my teammate's no matter which way it faced.
Clothing is all that remains. All my gear, gone.
