Cannot get rid of Heir of Desire curse from Antique Jeweled Ring

You need to complete a fortune aspiration. When you’ve completed it, you will have disabled the curse. All you need to do then is click on your sim and an action bubble will pop up letting you disable it. You may have to select more choices a couple times before you see it. Hopefully that helps. It took me a while to figure it out as well. 

I'm having the same problem as well. I have two sims that I have no idea how they put the ring on, but I cant get rid of. Also not modded or anything. Ive completed multiple fortune aspirations and still cant take the ring off.

The issue is the curse keeps coming back, I put it on my sim who has completed a fortune aspiration clicked through found the option to disable the curse and even got a positive mood let to reflect that. Then I traveled off lot and the curse moodlet came right back

So when it says complete a fortune aspiration, does that mean like the entire aspiration or would a milestone suffice? e.g. I just completed the "Going for Not Broke" milestone for the Fabulously Wealthy aspiration and I'm still not able to disable it. I put it on my teen sim and took it right off after finding this out but the curse is still there. I feel like she's gonna be uncomfortable for a long time lmao

The WHOLE aspiration. Not just a milestone or a stage. The whole aspiration. 
you have to complete the entire 4 stages of the “fabulously wealthy” or the other one. 
I said screw it and motherloded through because this was getting stupid. I don’t even know HOW I got this stupid ring/curse in the fist place. 
I’ve disabled it. I thought, okay maybe I just have to go through and disable on all outfits and be good. Nope. 
Can get it off in CAS. Have to CONTINUOUSLY disable the stupid curse. And can’t even get someone else to take the **bleep** ring (which I’ve read hasn’t even been working for people). 
this is getting ridiculous and I’m about done playing. 
I was without my computer for about 8months while my husband did a full rebuild of both our computers and I come back to this crap. I’m not impressed. 

I’ve done all that and it keeps coming back. It’s hella bugged. You have to disable to curse every outfit change. Every move between lots. 

Oh wow that's a hefty consequence for something so small lol. Yeah that is frustrating, thanks for clarifying.

I also have a problem where my sim just randomly got the uncomfortable buff from the cursed ring out of nowhere, it just happened when he got out of bed in the morning. At first I thought it was a bug but then I noticed he had just started randomly wearing the ring (???) without me even adding it on him in CAS. He just had it on for no reason whatsoever even though I've literally avoided adding it onto any of my sims since getting the item (because I learned about the curse through forums and it sounded pretty annoying lol). 

Don't know if this matters but I completed the event on Tuesday and after completing it I added Marina Corsair to another household (not the one I currently have this problem with) with cheats because there was no option to ask her to move in. Curious if other people have had similar issues.

(No mods no CC etc. etc.)

Now I also noticed he doesn't even have the ring on any of his outfits when I go to CAS, he only has it on live mode for some reason?

I jumped into a house with a pre-made island living townie today (Leila) and had this exact thing happening with her, I was confused as to how she even had the ring on and then I went into CAS and she wasn't wearing it. If I cheated the moodlet away the ring would vanish but then every time I traveled with her the moodlet and ring would reappear 

Even after completing the entire fortune aspiration and disabling the curse, the mood buff keeps popping up. I even removed the ring in CAS and it still keeps popping up. The ring is 1000% bugged 😭

So much this.  It's not even just when you travel; going into build / buy mode or CAS also re-triggers the curse.  Or napping, apparently.  Every time I look at the moodlets of the noble I put the ring on, they have the curse moodlet, the curse removed moodlet, OR BOTH.

If anyone is still having this problem (just happened to me) here's the cheat to get rid of it: traits.remove_trait Trait_LiveEvent_CursedRing
