Can you be more specific? Is there an example you can give?

The current set of parameters have trouble to fit the continuum when it rises very strongly in the 10-15um region. Also it sometimes uses the dust feature at ~33um to compensate for the lack of continuum in the fit at the longer wavelengths.

Do you have an example, @els1 ?

I often turn off 33µm dust for that reason. That was a predicted graphite band that never materialized. Are you sure these types of issues aren't caused by attenuation/extinction? In my experience (of mostly galaxy spectra) that's almost always what makes PAHFIT miss the continuum level badly.
