[OPEN] Reloading the game while Sim is dying produces tombstone

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.63.136.1010
What expansions, game packs, and stuff packs do you have installed? All of Them
Steps: How can we find the bug ourselves? Sim is dying by accident. In effort to save The Sim, without going through Resurrection, Go to Manage World/ Exit to Main Menu without saving Progress. (Don't remember, which option I chose.)
What happens when the bug occurs? The Sim is alive, in previous Save, by not saving Progress in Exiting to Manage Worlds/ Exit to Main Menu. The Problem occurs when I reenter the Household again. Sims personal Inventory is now duplicated in Household inventory, alongside their Gravestone/Urn.
What do you expect to see? The Sims Items in personal Inventory of course. - No double up in Household Inventory, and no Gravestone/Urn either. - As The Sim never died in the former Save.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes
Did this issue appear after a specific patch or change you made to your system? No

‌

It happened 2-3 times.(Out of 2-3 unwanted Deaths/Life Saving attempts)  It isn't a recent Problem, but I do ponder if Others have experienced the Same.

I don't like killing of my Sims. - But They do sometimes, by Themselves, do stupid things like start Drowning or Getting Electrocuted etc.

In attempt to save Their Life, I Exit to either Manage World or Exit to Main Menu without saving Progress. (Can't remember my Choice.) - And get Double up in Items in return. 

Haven't got any Pictures of the Household Inventory. I've deleted unnecessary Items (like my Undead Sims Harvestables/Collectibles/Spices and Whatnot's) due to reduce an unrelated Issue.
