First the points were adjusted due to a benchmarking problem. The deadlines were adjusted at the same time. Once the problem with the deadlines was discovered, it, too was corrected which significantly changed the bonus factor. I don't know exactly when either of those events happened so it's possible that almost anything happened to your bonus.
... and there's always the usual list of possible explanations for the loss of QRB points: Download and upload with a different UserName or with a different passkey ... or a change of either a passkey or UserName causing the new combination to require 10 more non-bonus WUs.
my id&passkey has not changed .The only changed is I upgraded from 7.1.38 to 7.1.43. config file is same.
Maybe this is a problem of 7.1.43.BTW, I finished that WU in about 7 hours.
Hardware configuration: Intel i7-4770K @ 4.5 GHz, 16 GB DDR3-2133 Corsair Vengence (black/red), EVGA GTX 760 @ 1200 MHz, on an Asus Maximus VI Hero MB (black/red), in a blacked out Antec P280 Tower, with a Xigmatek Night Hawk (black) HSF, Seasonic 760w Platinum (black case, sleeves, wires), 4 SilenX 120mm Case fans with silicon fan gaskets and silicon mounts (all black), a 512GB Samsung SSD (black), and a 2TB Black Western Digital HD (silver/black).
I quit FAH temporarily for some personal reasons after that WU.
I will restart FAH in next few days to see If my bonus point is correct for next WU.Waiting for reply...
