So recently I finally had the cash and was able to upgrade from the base game I got as part of the Kickstarter to the full Season Pass. I had an in progress campaign I was a few missions into and am now pushing deep into but I'm noticing none of the DLC content seems to be affecting the campaign. Now I completely understand it won't change story missions but even side missions and random contracts don't seem to be effected. Is this because I had started it before purchasing the DLC? Does the DLC only work in skirmish and career modes? I just don't understand why I'm not seeing any of the additional content.
