The Sims Medieval Pirates and Nobles suddenly avaliable

So I may be just being daft, but a while ago (I can't remember the exact number of days or weeks, because life (for so many people) has been very busy, and I wasn't paying that much attention) I remember noticing that I had a new DLC or expansion pack notification come up, and although I thought it was for the Sims 4, I'm not 100% sure.

Now, today, deciding to download The Sims Medieval again, I find that it had Pirates and Nobles for download too. Now, it has been YEARS since I've played this game, and I have the limited edition, which according to Origin, I 'added to my library' in 2015. I don't remember the DLC being included, but I suppose it's possible it's just my memory. I have noticed that you cannot buy the DLC induvidually anymore from Origin, which I find interesting. I wish there was a way to see when specific add on content was added.

I have searched as far back as I am able in my downloads, and cannot find anything to suggest I bought this DLC recently. Am I missing something here?

I downloaded it, and started up the game, everything works fine and I'm reasonably sure I don't remeber there being the other options (added from the DLC) being avaliable before. I will also, in the meantime, continue playing, since I cannot see a way to uninstal that DLC, unlike the Sims 3. (Yes I know I can just unistall and redownload, but I just would rather not unless I have to.)

I am currently trying to get word from EA help, but I know they're very busy, and there isn't really a set topic this issue falls under, that I can work out.  Your suggestions would be apprieciated, thank you.
