Use case: We have Quick user object; users have familyMembersChildren (hasManyThrough → Child) and familyMembers have mostRecentRegistrations (hasOne).

If I get a user and a mementify it to ask for familyMembersChildren it works as expected with an array of children attached to each user.

If I ask for familyMembersChildren and familyMembersChildren.mostRecentRegistration – then I get the mostRecentRegistration record in place of the child record, e.g. instead of

I get

Our investigation suggests that getMemento(includes=["foo", "foo.bar"], ignoreDefaults=true) means "recursively mementify foo, but, because nested child includes have been mentioned, recursively apply ignore defaults"modules/mementifier/interceptors/Mementifier.cfc:357 

Because ignoredefaults=true with an includes list of ["bar"] means "mementify this thing exactly just with bar"`

In other words: mementifier doesn’t like it if you ask for [root.thing] as well as [root.thing.childThing]

Tested this on Mementifier v2 and v3 (current). Quick is v4 but I don’t think this has anything to do with Quick exactly.
