Steps: How can we find the bug ourselves? The way that you find this bug is by creating a family or a married couple in Create a Sim. You do mention that they are husband and wife, or husband and husband, or wife and wife. But the bug occurs when you start playing the game.
What happens when the bug occurs? It happens when you choose one of the family aspirations or if you click on one of the couple. One of the family aspirations requires the sim to get married. This is a problem when you've already created a married couple in CAS. I do also see choices of wanting to date the sim that you are married to or asking them to be your boyfriend/girlfriend when they are already are married. I've even see the proposal option when I've created them married already.
What do you expect to see? A way for the system to recognize the married couple sims created in CAS to know that they are married.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes
Did this issue appear after a specific patch or change you made to your system? No

First off, I cannot find the latest version of the game because all I see at the bottom of the screen are the requirements and the address of EA. But I am currently waiting for my laptop to be fixed. By the time it does, it will update to the latest version when the new expansion pack comes.

And the other thing that I expect to see where I can find the game version more clearly. If it is in the Requirements, where is it?

But I have noticed this issue quite a few times after creating a married couple in CAS that the game doesn't recognize that they are married, whether it is through Family Aspiration or by clicking on them. I have seen one of the options while click on the Married Sim to be Boyfriend/Girlfriend or even the proposal option. I don't want to marry them again.

Anyway, I thought that I might bring this to your attention.

If you are asking for a screenshot, I will not be doing that until I get my laptop fixed. The one that I am writing to you on right now, is old doesn't have the space for the mods that I have.
