I was working with `sourcehan[serif/sans].ttc`.

Looks fine. It seems that ConTeXt parses the large `SourceHanSerif` font files
and generates separate CJK font families for the different regional variants
(SC, TC, HC, J, and K).
However, if I run the reload command again without `--force`, the system
apparently reuses the hashed values and changed the database with the output
asfollow:
```
mtxrun --script fonts --list --all --pattern='sourcehanserif'
```
```
identifier familyname fontname
filename subfont
instances
sourcehanserifhc sourcehanserifhc sourcehanserifhcregular

```
In this case, only the **HC family** appears, and the SC/TC/K variants
disappear.
Do you also have the separate files on your system? In that case you
might get clashes in font names (same key -> different files). The same
can happen with variables fonts that have embedded instance names, in
which case one should choose either to use a variable font or the
dedicated instance files.
