@Scorpina2009 I haven't been playing TS3 too much since they made the update that added this feature into the Launcher, but as far as I know if you have any of your games installed as a download through Origin you must select what expansions you want loaded up when you play the game. I found this really frustrating because I thought if I downloaded my expansions that they would just load up when I went to play, but now every time I go in it asks which expansions I want active and yells at me not to play more than recommended. If I only wanted to add one or two expansions in to the base game I would've bought only two expansions, instead of buying them all and then only getting to play with a couple at a time for performance reasons. I don't know the ramifications for if you load up a couple expansions for one play session and then uncheck those for the next time through, but I would assume that it would either corrupt the save or you would lose any progress that is linked to the expansion that is no longer active.
