Factorio v1.1.61
I was driving around my car, clicking in zoomed in map view, killing some enemies. It worked fine for a while but then I got this:

The mod Autodrive (1.1.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event autodrive::on_player_selected_area (ID 51)

Thanks for the report! Looks like enemies were out killing some cars as well. I've added a validity check. Can you confirm that this fixes the issue. :-)

Clicking after a car has died or just randomly usually doesn't crash the game. I can't reproduce it (before update) so hard to tell if it's fixed. But if you found an error with the code indicated by the error message then that's great, thanks :)

You're welcome! I've marked this as fixed for now (and I suppose it really is), but if you get another crash, just reopen this. :-D
