Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Question about cross-saves

I know the Switch platform does not natively support achievements like Steam does (which is a minor annoyance to me, as it helps me track my progression and work towards completing specific goals, but that is not something under your control). But with cross-saves between the Switch and Steam, will I earn the achievements on the Steam side when the saves sync / retroactively if I load the save file on Steam, or are they only earned if you satisfy the conditions while playing on the Steam version?

They are only earned if you satisfy the conditions while playing the Steam version. If you save before starting/completing relevant events, you can load the save in Steam and re-do it. However, that would require either knowing when achievements are triggered (which could involve spoilers for a first playthrough) or frequent saving (to limit how much you would need to re-do).
