The calculation of pour units has been improved to also attach non-solid items into overlapping pour objects. In some situations, items that are not overlapping are attached based on the bounding box of the non-solid item.
If you open a model where the pour units have already been calculated before this calculation improvement and the model contains non-solid items, these non-solid items are not included in the pour units until you run the Reset all pour unit relations except manual assignments command from the Quick Launch.
