Call to a member function getEnergy() on null

Can this patch be updated to create a new radioactivity entity if there is a field reference but no entity? The module does not create entities when we add a new radioactivity field to a content type/taxonomy/etc. with exiting content.

It seems sensible to (offer an option to) create entities on demand. The downside of doing so is we have to call save() on the entity during processing, which may trigger a lot of other activity, including adding the node to a workflow queue.

Option B is to update the field data directly without calling save() on the parent entity, which bypasses revision histories and may have its own issues.
