Antediluvian Alumni (trait) does not function.

    Starting a game, it does not reveal the Academy.

    Progression on reputation is not affected by the trait.

    Donation of a system does not relinquish control of the system nor does it contribute to reputation progression.

    It does however, add the prompt to donate a system to the Academy.

The Academy Reputation progression

    The Research technology has no affect on its progress nor does it add a 20% bonus on future progression.

     Building the one-time enhancement for 100% progression, has no affect on the reputation progression and does not award a Hero on the following turn.

I suppose it is worth adding that I am experiencing this bug without any additional DLC on the steam platform, save the digital deluxe upgrade.

This bug was probably introduced with the Awakening expansion and it would probably fix the issue, but I am not prepared to purchase an expansion based on what I know about this bug currently.
