That was one of the problems by leaving out the I however then by consecutively computing the expression

ToTFI[-(1/D)8 CA^3 FeynAmpDenominator[PropagatorDenominator[Momentum[p2,D],mE],PropagatorDenominator[Momentum[p2,D],mE]] Pair[LorentzIndex[Lor1,D],LorentzIndex[Lor2,D]] SMP[“g_s”]^6 Subscript[zeta, 1] SUNDelta[SUNIndex[a],SUNIndex[b]],p1,p2,q]

gives a similar behaviour as before

-(1/D)8 Subscript[zeta, 1] Subsuperscript[C, A, 3] Subsuperscript[g, s, 6] \[Delta]^(ab) g^(Lor1Lor2) Global`ToTFI`Private`dq1^Global`ToTFI`Private`a1.Global`ToTFI`Private`dq2^Global`ToTFI`Private`a2.Global`ToTFI`Private`pq1^Global`ToTFI`Private`s3.Global`ToTFI`Private`pq2^Global`ToTFI`Private`s4.Global`ToTFI`Private`q1q1^Global`ToTFI`Private`s1.Global`ToTFI`Private`q1q2^Global`ToTFI`Private`s5.Global`ToTFI`Private`q2q2^Global`ToTFI`Private`s2.Global`ToTFI`Private`c1(Global`ToTFI`Private`FakeMass)^(Global`ToTFI`Private`n1+1).Global`ToTFI`Private`c2(mE)^(Global`ToTFI`Private`n2+2).Global`ToTFI`Private`c2(Global`ToTFI`Private`mM)^(Global`ToTFI`Private`n2+1).Global`ToTFI`Private`c3(Global`ToTFI`Private`FakeMass)^(Global`ToTFI`Private`n3+1).Global`ToTFI`Private`c4(Global`ToTFI`Private`FakeMass)^(Global`ToTFI`Private`n4+1).Global`ToTFI`Private`c5(Global`ToTFI`Private`FakeMass)^(Global`ToTFI`Private`n5+1)

It appears to me that always after loading Tarcer it works for the first expression but then fails for a few specific ones later on.

Cheers,
Philipp
