@xalioth still an issue for e.g. C/2022 E3 (see also #172 ) this feels like development is stalling?

[ssystem_minor.ini.txt](https://github.com/Stellarium/stellarium/files/13888949/ssystem_minor.ini.txt) that could explain it, even if it's conceptually not OK. in such a case, **at least a warning should be issued** for the missing objects. the user should be...
