and while you haven't fixed the problem which you didn't even describe
properly, you have worked aropund it.
It may return and hit you back, again, even harder.

maybe you should describe it more deeply.

slave hosts the zone too.

no, delegation is not dns server pointing. It's the zone having NS records
for subzone.

I can guess you failed to do this, so while your master knows where the
subzone is, slave does not.
