No badge credit for SSA2 Troll Bosses
It might be, since they're not 'normal' trolls.
When you target them, what is their faction? Does it say "Trolls" or something else?

It's common when new enemies are added to the game files that some bit of code or whatever gets left out that makes enemies tally for certain badges. It is rather routine to see: "X now count for the Y Badge" get added to patch notes. It is likely an oversight. Toss a /bug at it and maybe also PM Zwill asking him to forward the info to the appropriate Dev (unless you happen to know who the badge Dev is, I am not sure... though I seem to recall TheNet taking a shine to them).
Edit: Also, check the faction first as Ironblade suggests.
I suppose it's my fault for not checking first, but I just ran the first mission of Pandora's Box at x8 to try and work on my troll bosses badge. I like to check my progress after a mission because I feel it goes faster that way (kind of like not looking at the clock during school or work), but when I checked I hadn't gotten credit for even a single boss.
Is this WAI?
