I've installed Oblivion GOTY on my XBox One, when I did this I used Disc One of the two discs in the case. I found out today (and several hours into my game) that in order to have my XBox One 'see' the other DLC included with the GOTY Edition I actually have to install Disc 2 from the start.
My worry is that by uninstalling the game I'll also lose all progress I've made thus far. When I go to Manage Game I do see there's a section for 'Saved Data' that's 10MB, if I uninstall the game itself but leave this section intact, will I still have my saved games when I re-install with the DLC?
