[NTG-context] Mutiple citations doesn't work with compress=no + interaction

I know that if I want to have clickable hyperlinks for citations, I need to turn off 'compress' for the citation type: \setupcite[authoryears][compress=no] The problem is that this doesn't seem to work: I get an 'unknown reference' error. references : unknown reference [][Balachandran2008 references : unknown reference [][Balachandran2008 references : unknown reference [][Balachandran2008 Strangely, this only happens when I want to refer to multiple authors, e.g. \cite[ref1, ref2, ref3], and everything works fine if I just do \cite[ref1]. I've attached a minimal example. Where am I going wrong? -- Michael Murphy
