@teralitha I'll see if I can fix the power gifting back when I next work through some minor changes (no time for current release though as it needed releasing today due to the upcoming rainbow cup but I did notice in a couple of the testing replays that the conditions were met for power to be gifted back yet it wasnt). It's not a big priority though as it just means the AI misses out on a small amount of reclaim.
Hopefully you should notice a difference with protecting the base against experimentals (it's probably still not enough to actually stop the experimental, but is more noticeable than before where sometimes almost nothing would be done)
Re navy it's working as intended - M27 will work with other M27 for navy, but not with non-M27 (since it has no control over how the non-M27 navy is used). How effective the 'coordination' approach is varies depending on the map (basically it's worse if the M27 start positions are far away from each other/closer to the enemy than each other). As the navy's still in it's early days it also doesnt have much logic re when it's better to stop building navy and focus on ecoing up, but I may not add that anyway (due to the risk of stopping naval production and losing navy, allowing the enemy to then destroy all of your eco with ships)
