Hi Will,
I suspect that this might be related to the recent change in the syntax of
PropagatorDenominator in FeynArts
<https://github.com/FeynCalc/feynarts-mirror/commit/73094019d93c8a11cf8eee7189e5514a8e9154d6#diff-cc9305310a3b0771b5c2045c39d7cc73R491>
This should only concern propagators raised to some powers and my examples
from the test suite (including self-energies with gauge terms) seem to
work fine.
Could you please send me the output of CreateFeynAmp for one of the
diagrams that
generates this sort of ouput:
CreateFeynAmp[...]//InputForm
Cheers,
Vladyslav
