Okay gals and guys. I found this shortly after I posted my reply on January 6, but I forgot to post it here too.
Apparently, DICE already knows about the issue and they are working on a fix. In the meantime, you can still receive the trophy if the timer runs out on the match (which is why some people have it even though it appears to be a dud trophy). This sucks because when you put in 35 kills by yourself, the match only lasts five minutes, but hey - they know, and eventually we will (hopefully) have a patch for it. Why they don't just lower the timer to five minutes, I don't really know...it's not like Blast lasts longer than five or six anyway.
