When a car with a player inside gets destroyed by biters the server will crash in a map using the pvp(modified) scenario.
Original post is https://forums.factorio.com/viewtopic.php?f=23&t=59631.

The version of PvP Scenario used is 1.3.3.

Fixed starting with version 1.3.4

Instructions for updating scripts in the save will be written later

1) Need to find path to save (wiki)
p.s. for me: "%appdata%\Factorio\saves"
2) Backup the save (because something can goes wrong)
3) Download the new version of the mod

Variant A (simply, but not working always)

A.1) Go to the folder "...\pack-scenarios_1.3.4\scenarios"
A.2) Pick scenario and open him, example: "pvp(modified)"
A.3) Copy all files from "pvp(modified)", then replace all files in the save

Variant B

B.1) Delete all files in the save except "level.dat", "level-init.dat", "preview.png", "script.dat", "replay.dat", "blueprint.dat" and "info.json" (I hope you understand that all important files is *.dat Do not worry if there are not some)
B.2) Go to the folder "...\pack-scenarios_1.3.4\scenarios"
B.3) Pick scenario and open him, example: "pvp(modified)"
B.4) Copy all files from "pvp(modified)" and paste all files in the save

If there are problems in the game, it can sometimes help to write in the console: "/c game.reload_script()"
