So this crash is a bit unusual and I don't fully understand how the above error is related to what I'm seeing in game. I originally thought the crash was slave-related (which took buying and selling each individual slave to find out), but it's actually related to an equipped item.
From the Umbra market Magic Item Exchange, I received a Lacy Underwear with the following (green text) enhanced attributes +5 Luxury & +5 Lust per day.
If the item is equipped on any slave, the game will crash on day end. If the item is held in the chest or bag, the day will end normally with no issues. With the debug mod exe installed, it will actually go to the next day without crashing (while equipped to a slave), but will not display an end-of-day report.
Good news, I know what the problem is, so the game can proceed normally. Bad news, can't fully trust items from the Umbra exchange and unfortunately seems to be the only place to receive items with certain/better attributes.
