The MWE
\index{sample}
\index{fun+games}\index{fun+stuff}
\index{fun}
\seeindex{fun}{sample} % with first subheading, not heading
\seeindex{fun}{blah} % shown with heading (as it should be) ONLY if
\index{fun} is commented out; otherwise it is not shown
\seeindex{fun}{humbug} % not shown
\seeinde
In latest beta, the error got bigger:
\starttext
\index{sample}
\index{Fun+games}\index{Fun+stuff}
\seeindex{Fun}{sample}
\seeindex{Fun}{bug} % missing!
\seeindex{Fun}{blah}
\placeindex[n=1]
\stoptext
now gives
f
Fun see blah
games , see sample
stuff
s
sample
i.e.
* multiple seeindex refere
