Plants vs Zombies Garden Warfare dlc achievements dlc dont work

I found the solution to the issue I had with the non DLC achievements not popping. I hadn't downloaded all the DLC for the game. I assumed it did that automatically with the updates but it obviously didn't. Last night I switched on my xbox & scrolled across to the games section. I opened up "My games" & located PvZ. Pressed the X button for game details & scrolled along to the DLC. Selected "See All" & I noticed a couple of the free DLC's hadn't been dowloaded as they weren't ticked. I think one was called "Zomboss Down" & the other was "Garden Variety Down" or something like that. One was about 612MB in size & the other was 212MB. So I downloaded both of those, waited for them to finish & then launched the game. Upon getting to the main menu about 5-6 DLC achievements popped. I told a couple of my friends who had the same issue about this & can confirm this sorted out their DLC achievement problem too. I hope this helps some of you guys as if it does we can now work on those achievements again.
