Old Title: [0.18.17] Crash using "--instrument-mod" "debugadapter" in specific use case

I'm logging this here first rather than with JustARandomGeek as its a hard game crash. However, I fully appreciate that the issue is surfacing from the vsCode extension and so it may not be an interest to other than him.

With a the attached muppet_streamer mod extract it to a folder in the Factorio mods folder.
Open the mod folder in VS Code with the debug adpater.
Add a breakpoint on scripts\leaky-flamethrower.lua line 85.
Run the game within the VSCode debugger.
Start a new game
Kill the player: /c game.player.character.die()
Click respawn and before the respawn timer completes do the next step.
Run the command to trigger the mod replacing "muppet9010" with your player name: /muppet_streamer_leaky_flamethrower {"delay":0, "ammoCount":5, "target":"muppet9010"}
The breakpoint will be hit in VS Code
In VScode hover over the variable "targetPlayer" on the line 85.
Give the game a second and the game will crash.

After some digging, this same crash is also reproduced by `/c game.print(game.player.entity_copy_source.valid)` while the current player is dead, even without my debugger attached, so it looks like this is a base game bug that I simply revealed by attempting to access every possible property.

A more correct title is probably "Crash when accessing LuaPlayer.entity_copy_source while player is dead"

title updated, thanks for the help by looking at this. you obviously know far too much

Thanks for the report. It's now fixed for the next release.
