A cyclic reference was encountered during evaluation.

Hi All,

I have the same issue running 2.68.5432.841 64-bit (April, 2019).

The report refreshes well since updating to the April 2019 release for nearly a year.

Now it randomly fails with " A cyclic reference was encountered...."

The related table is a "composition" of four appended tables - maybe this is a hint.
