Reset Campaign didn't delete all campaign's savegames
So in order to replay the updated original campaign, I reset my progress, but some of my saves are still here. I still have saves for levels 2 and 3, all v1.4. I also have saves for the levels 7, 10 and the Awakening from v1.2.
This sounds correct, resetting the campaign should only reset your progress on the campaign map. Save files will not be deleted.
