Hi, I created and started a dedicated Factorio server with Krastorio 2 spaced out. The server crashed after a player joined and then left shortly afterwards. It managed to restart, but crashed again whenever someone tried to join the game. I loaded the map in single-player mode and received the following error message:

The mod Leave Corpse On Exit (2.0.0) caused a non-recoverable error.
Please report this error to the mod author.
