From @mmarum-sugarcrm:
This is a use case we should consider adding to Professor M once we’ve achieved resolution here.

Basically, we’re hitting a JOIN limit when a large number of relationships exist. This is relatively common, especially when there are lots of custom modules, so we should consider how many we want to add. In particular, is there a hard limit we should consider.
