I have been paying attention to whether MNs get paid correctly during the upgrade. I did not expect these MNs getting paid correctly during the upgrade period. But, I just noticed something on dashninja.pl:

320215100%XhAGGdSgfPkHtkH9teXCJdZbnJAoSqTqJg
That 320215 block was reported to be paid to XhAGGdSgfPkHtkH9teXCJdZbnJAoSqTqJg but it actually goes into XbQzpQCk5kC5NPDDwDV2GdZMH7HrEe91hE as you can see here:

As I said, MNs not getting the correct payment during this period is not what I am complaining, I am just afraid that things will get undetected like this one. There is no indication from dashninja.pl about this particular wrong payment.
