it was my forth time doing the Spectre Mastery challenge. i had already done the 2500 waves and 5000 medals; all i needed was the 25 mil points earned.
when i finally completed the 25 mil points, i went back to the challenge list, only to find that the board said that i had completed the 25 mil component for the 4th time, the 2500 waves for the 4th time....but the 5000 medals for the 3rd time
i have lost 600 points towards my challenge score and now i cannot do that challenge again because it has glitched .......please fix this glitch, as it seems to be spreading
i have 2 other friends on my xbox list that this has happened to as well
