So I have not read all the responses here but in the ones I have read I haven't seen what I am experiencing. Yes, I have mods including CAS CC and MCCC, however I am experiencing the same issue with or without them.
The first time I started receiving the 532 save error was after I had just aged up my child to a teen. All of a sudden my game was refusing to save and reverted back to when they were still a child. Exited my game, went back in and all was well, my child aged up and my game saved no problem. I continued to play for a while and then started receiving the game save error after my teen when to the high school for the first time.
Long story short, I don't know how but all of a sudden, 2 of my days later when I started playing again (same family, same everything, I changed nothing), it worked. I was saving just fine, my teen was going to school, all was well.
Then, I sent my teen to the Thrift Store and started having issues again when I tried to create a Trendi Outfit. Time was reverting back again and would not save. I don't remember what I did to work around that, but somehow I did and got my game back on track, progressing normally with no save issues.
At this point, my teen has lived 1.5 sim weeks with no problems. All of a sudden, out of no where, I'm getting the save issue again. This time I realized that prior to 6AM sim time my game will save with no issue, after 6AM sim time, I get the save error with or without mods. At the same time, I keep getting the notification that it is Thanksgiving even though the calendar says it should be tomorrow.
I'm so confused and annoyed.
