Wow. The only trouble I've run into, so far, is that I had to remove the relationship from my young married couple to rid them of the bug that won't allow them to interact romantically. I used a mod, MCCC to do this. Then I took them into CAS to restore their marital state, because rebuilding the steps to achieve his ability to ask her to marry him was taking way too long. I used the cheat: cas.fulleditmode, and for the first time ever I was denied, as I got the message unable to edit an existing Sim. Face/palm. I've done it before you unintelligent mass of coding. (Not the exact verbiage I used at the time.) I did end up clearing their marriage relationship via MCCC, then I was able to make them spouses again. Phew, what a bunch of hoops I had to go through. All of this to say, I feel your pain.
