Hello,I think I've experienced a severe bug here. Consider the following:\setuphead[chapter][%referenceprefix={chapter},]...\cite[xxx]...\startpublication[k={xxx},t={...},a={...},y={...},]...\stoppublication\startchapter[title={BIBLIOGRAPHY}]\whitespace\placepublications\stopchapterwill render [[error 2]] in place of `\cite[xxx]' because of `referenceprefix' in `\setuphead'. Why? I don't believe `referenceprefix' in `\setuphead' should have something to do with `\cite' at all.Thankfully, it's pretty rare that one uses `chapter' for bibliography, but still I think it's better to fix this. For instance, right now the following works fine for me:\setuphead[chapter][%referenceprefix={chapter},]\setuphead[title][%referenceprefix={},]...\cite[xxx]...\startpublication[k={xxx},t={...},a={...},y={...},]...\stoppublication\starttitle[title={BIBLIOGRAPHY}]\whitespace\placepublications\stoptitleNOTE: It's extremely important to explicitly do `referenceprefix={}' for `title' because somehow `title' inherits `referenceprefix={chapter}' from `chapter'; and therefore, not doing `referenceprefix={}' will again result in [[error 2]] in place of `\cite[xxx]'.Looking forward to your feedback.Kind regards,Alexander
