Finderski said: If you've already redeemed your code, the additional items should automatically be added. At least they were for me. When I checked my Humble Bundle, I couldn't find a new code, so went to My Market Place items and filtered it by Bundles, and all the new items that were added after I initially purchased the bundle were in My Marketplace Items already. I heard from friends of mine who purchased the bundle saying they got a second code via Humble Bundle and after Inputing that , they got everything. It seems the first code they got was made invalid and it also seems that all further purchases of that bundle only got one code... And as you said, it should auto update... ^^
