Error while running event Oil_Patches_Organizer-0_18::on_chunk_generated (ID 12)

That's odd. It should only be looking for things that can be 'mined' using the vanilla pumpjack.

Can I get a list of the mods you are using that add new resources so I can test against them?

Not a fix, but it will explicitly crash with an error message if it can't find any resources to arrange (which would result in attempt to arrange everything).

It will also list the resources it will attempt to arrange in the log.

The only mod that adds new resources would be space exploration. It is noteworthy that the organizer was running fine without any errors until I updated to the newest factorio version. Perhaps something is related.
Strangely enough it also did not happen during new chunk discovery. I was well within active radar range, and all surrounding area has been mapped by my radars a long time ago.

Disabling the auto organization during generation made it stop, I don't know if I can reproduce it now.

I now explicitly check for and crash with a helpful error message if a non-resource entity is, somehow, added to the list of entities to organize.

Updated the mod version, will post if it occurs again. Thank you very much for maintaining this mod!
