Also I found out there is a Mod that may be causing this issue too, when trying to fix my friend’s game. The mod is from Waronk file called Waronk_SkateScooter_Complete. I will be reaching out to the creator.
I am having this same issue and I tried all the suggestions including @crinrict's suggestion of resetting the game files. It fixed the issue for the new save that I made but sadly did not fix it for the save I have actually been playing in. I am repairing the game right now to see if that fixes it but I am not hopeful.
@barbedwirebutch Just make a backup copy of the saves you want to experiment with. That way, even if you completely bork the saves, you can revert to the previous copies with no (more) harm done.
For the sims that have already been turned, you may want to use a mod or an in-game method to turn them human again, at least until you get this sorted out.
well, it affects gameplay in the sense that i can't visit the new world. i don't know which is the "correct" world, and i don't want to cause problems later on down the line.
Thank youuuuu sooooo much it worked for me I tried fixing it for 2 days and your solution worked directly thank you so so much

Steps: How can we find the bug ourselves? Werewolves game pack and Cottage Living
What happens when the bug occurs? there are 2 Moonwood Mill worlds so I have duplicates of many Sims that came with the Werewolves pack and in Cottage Living the second ribbon for milk, wool, eggs, pie, flowers does not get added to my Sims inventory or house inventory
What do you expect to see? I would like to not have duplicates of the same worlds or Sims and I would like to see the second ribbon for the fair not glitch and be added to the Sims inventory or house inventory
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? No
With the second ribbon from the fair in Cottage Living its not a make or break thing it is just annoying when you bake a pie, or bring wool, or milk, etc and then not even have a mention if you came in second place or last or not at all is weird, it worked when it first came out and then the next patch update after it never seemed to end up working.
And the double Moonwood Mill is self explanatory, there's also duplicate Sims, makes it confusing.
