[Question] Flattened action space in chess env

Question

Hi
I was looking how chess was written in petting zoo and I found action is flatten from 8x8x73 to 4672 and that it can be unflattened using given equations. The problem is i checked them and they give incorrect outputs. Am I doing something wrong?

I believe this is solved in #1004 (edit, nvm it was another pr)

Looks like it was in this PR instead, but the docstring doesn't follow the convention for which we can check automatically (using >>>, gymnasium has examples this way), so I will update it so that the CI checks that these calculations work correctly
