We have been working with asymmetric (around local y-axis) cross sections in Karamba 1.3.2 and found some strange behaviour, specifically I-sections modified to become a T (the behaviour I am describing here is consistent for any asymmetric I-sections though).
Below you can see I am setting a simple cross section. The input has the T upside down (so web is top), whereas in the output of the cross section component, the T is flipped! In beam view, however, the cross section corresponds to my original input.
Now looking at the results I see some similar inconsistencies. The beam view results and legend seem to correspond to the input that I have given (and are correct). The beam results, however, (min max stress and moments) are not.
I have attached a simple script replicating the problem as well.
It seems to occur in Karamba 1.3.2 and 1.3.1. Is this a known problem? Has this been solved in 1.3.3?

Would be great if you could help out!
