Hi Maxim,
many thanks for the bug report. I'll upload the fix tomorrow, but for the moment you can just use the option SUNTraceEvaluate->True, which is set to Automatic by default.

Did you try to reinstall FeynCalc (stable version) using the automatic installer to make sure that you have the latest bugfixes? No, should I?
Hi, everyone evaluating
SUNSimplify[SUNTrace[SUNT[a, a, b, b]]] // InputForm
I get
SUNTrace[SUNT[SUNIndex[FCGV["sun16131"]]] . SUNT[SUNIndex[FCGV["sun16131"]]] . SUNT[SUNIndex[FCGV["sun16132"]]] . SUNT[SUNIndex[FCGV["sun16132"]]]]
while evaluating an equivalent expression
SUNSimplify[SUNTrace[SUNT[a, b, b, a]]] // InputForm
I get
CA*CF^2
as it should be.
So the cyclic property of the color trace doesn't seem to always work. Is it a known issue?
