The attached problematic input was extracted from the ClassicalMaximals package test suite: bug1.txt

Reading that file with the latest recog dev version gives this:

Since it involves recognition node (projective) C6, perhaps this is related to issue #295 ?

Another such error (derived from the TestTensorInducedDecompositionStabilizerInSp([2, 5, 3]); test in gap-packages/ClassicalMaximals#84): bug2.txt

Very curious: if the cvec package is loaded, both reproducers work. If it is not loaded, they fail.
