Nah, the hook on the Ride Engine hasn't been unbent by loops. It's just a shallower angle compared to the Mystic.
The times I noticed the chicken loop half off, it's been when the lines slack after a crash or if I catch up to the kite on landing a jump.
The CL would be half off hanging on the hook and just about to wiggle free of the donkey dick.
I've attached a couple of pics of the two different harnesses and it's considerably easier on the Ride engine hook to get it into that half unhooked position compared to the Mystic Stealth Bar.
I would hazard a guess that a larger CL would work its' way off easier compared to the small free-ride loop on the click bar.
