MM Zone 13 100 Kills Error

Last night(20-04-2011) I tried to do MM mission but an error occured.
I did 7 kills in the morning but when I came back at night to do the rest the kills were all gone but that´s not the worst...
After I did the 100 kills and won the "E" letter I logged in today to find out the mission didn´t count at all...I don´t have the E letter anymore and I didn´t get the XM1014- A(which was suppose to).
Please Z8 devs fix this bug so that it doesn´t happen anymore to all the CF players trying to do MM missions.
Thank you.
