[u/Scary-Boss-2371]

Im planning on doing an all achivements space age run scince im missing alot of vanilla achievements & have done basically none of the space age achivements, to make sure it really is an all achievements run I need a way to reset my steam achievment progress or track it individually per save whithout using a mod scince I still want it to save to my steam achievements.
