sims 4 installed twice
there are two full sims games downloaded on my computer. I noticed this when an extra shortcut kept popping up on my desktop, always coming back no matter how many times i tried deleting it. I think this happened around the same time i tried downloading a new expansion pack through origin instead of steam. All of the games reinstalled through origin and i couldnt stop them haha. I used to use origin to launch the sims 4 but recently switched to steam for convenience when the game was on sale. I want to uninstall one of them because my computer is hanging onto a thread with the amount of space this has left but I dont know which is which. they both look the same in the "apps & features" storage in my pc's settings.
How do I know which one to uninstall and can I safely do so without losing years worth of gameplay?
details: im using windows 10, I have all but 2 expansion packs, every game pack and a couple stuff packs. I use cc but not much. This started many months after starting to use steam. I only launch the game through steam now.
