Missing 20 bomb badge

Yesterday when I was playing, the game froze and lagged out when I got a 20 bomb on wattson. When I did eventually make it back to the lobby, it didn't save the game progress of the previous game. It showed when I was in a ranked match instead. I already had the 4k badge, so that wasn’t an issue, but when I did check the 4k badge, it didn’t have my overall damage from the previous game either. Is there any way that I can get help on getting the 20 kill badge for wattson on my account?
