Dear Kristopher,

thanks again for reporting this bug, it should be now fixed

https://github.com/FeynCalc/feyncalc/commit/34f514d7b698e2273aa8228ec39e8c97971006df

and

<< FeynCalc`
OneLoop[l, A.FAD[{p - l, m}] + B GAD[a]]A

returns

I*A*Pi^2*A0[m^2] + B*DiracGamma[LorentzIndex[a, D], D]

as it should.

Cheers,
Vladyslav
