This code block is really confusing me

It uses a try-except block to handle compatibility issues but the logic fails to capture the seed value in the successful cases.

• If rng is None: random.Random(None) succeeds, skipping the except block. seed remains None.
• If rng is an int: random.Random(int) succeeds, skipping the except block. seed remains None.

As a result, self._seed is set to None at the end of the block (self._seed = seed). This breaks reproducibility and causes model.scenario.rng to be None

Please correct me if I am wrong!
