Hi rococofall
I moved this to the bug forum but could you please do the following
Would be good if you could also test if the same happens if you do the same on a new save game with no mods/cc.
EDIT: Also moved the posts from the multi post over.
Thank you for your reply. I disabled all expansion packs except for Royalty & Legacy, removed all mods, and created a new save file. Here is the latest lastException I received.

Hi rococofall
to be sure, you just delete some families and got the error again or did you do something else ?
Would you be willing to share your save with me ?
If so, upload it somewhere like dropbox, googledrive or OneDrive and PM me the link.
The only thing I did was go to 'Manage Households', delete all the new expansion pack's default families, and save. After restarting the game, the error occurred when trying to load that save. No other actions were taken.
