SimGuruNick has responded about the saving error on the thread titled "Save Error 532"
I'm going to attempt trying without implementing cas.fulleditmode since that is one of my game starting rituals, inputting testingcheats (which I've also noticed something weird with since the last big update - cheat sim info and kill options have been severely decreased - might make a thread about that if anyone agrees), bb.moveobjects on, and cas.fulleditmode.
I am still getting the saving error outside of Copperdale, however I don't think I've had the groundhog day/losing time error since leaving Copperdale - and I know disabling the HSY pack didn't solve the save error for me.
I have gone into CAS once, either yesterday morning or the other night, without the cas.fulleditmode implemented and it did save right after so I'm slightly hopeful when I haven't been for the last few days.
I'll check in about the cas.fulleditmode for the saving error tonight
