Sorry to hear that (as an Onza 3 owner). Could you describe where's the spot?
Id take a picture but i already sent it in. but right around where you would put a limbsaver it is very hard to detect if your limbs are under load once you release the pressure on the limbs its plain as day just freguently run your nail across that part of your limb.
