I would appreciate some eyes on a patch I created for an error that occurs when you run a count calculation with multiple includes and at least one join. JoinDependency#graft does not set the parent join to the base join when a suitable parent is not found in the join dependency which causes an error when looking up the association to include.
The lighthouse ticket and patch can be found at https://rails.lighthouseapp.com/projects/8994/tickets/5124-patch-activerecord-count-fails-when-run-with-multiple-includes-and-a-join
