I absolutely love everything about the 6x42 except the reliability and the wide duplex. But, my failure rate over time of Leuopold scopes not holding zero to the point of moving 12" plus from shot-to-shot is probably 25-30 percent and none of them track. After fighting zero on a 6x42 after a long flight to Africa and using up 20 rounds to re-zero, I gave up on Leupolds and started voting elsewhere in the optics world with my money.
I bet I've had 50 Leupolds and love their features other than their quality is absolute junk---almost all of them. I hope they get it straightened out, but it would surprise me if they ever do.
