The attached guide from @atreya33 might help. It shows which rings go on which finger.
I've been using it on Xbox Series X to help me see where the jewellery goes. I find that when my Sims propose, the rings will just go to the assigned finger. So I think it's an oversight rather than a bug. The rings have to go on a particular finger.
I started using it because I found that rings were being removed when I added a new one. Then I realised that's because some rings were assigned to the same finger so some can't be worn together.
@simsplayer818 Thanks for sharing that! I hadn't paid attention and didn't realize the jewelry from Crystal Creations was being placed on specific fingers. Given that proposing with the rings is a pack feature, it would be nice if there was an override to place the engagement ring on the traditional ring finger. Maybe I'm just being "old fashioned" though. haha I have no idea how difficult it would be to change something like this. Anyway, thanks again!
