Hi guys I want to confirm that this is a bug. I've noticed some old threads on this [1] but I believe it's a little different.
When the master document includes the bibliography, opening the child document and adding a citation works. So, while editing, the child document is aware of the bib database. When compiling for preview, however, that knowledge is lost and citations are replaced with "(author?)" and the like. Obviously, there is no reference list for that child document. Wouldn't it be possible to actually integrate the child document while rendering? Do not show the references, but do show citations that are valid (i.e. that exists in the bib included in the master doc). You can reproduce this with a template [2].
