The attackmanager shouldnt even be loaded and that specific error is something I havent seen during the many times I have tested the master version of HC. Still, it could be possible that something went wrong with the deletion of said petra files in the released version on moddb somewhere.
It might be that .deleted file somehow, since the HC AI has been standalone for a while now.
It could also be an installation problem for all I know though.
Anyway, I would only consider the Hylians and the Gerudo being fully supported by the AI. Any other faction that has some AI, has not been edited by me personally. That was back during 0.8 I believe when Neph tried to make something work through the AI config data for those other factions.
On a side note, I am currently working on the Zora AI, which is showing some good progress already. When I get to them again, it might not take me more than a few days to flag them as 'supported' as well.
With regards to those list errors, once again, not exactly sure why the soldiers lists are empty or undefined somehow. I havent seen errors like that for a very long time.
Despite all of that, it is good to see that she enjoys HC as it currently stands. It is still a work in progress and the game is still far from balanced, but I believe we will get there eventually.
The team is eager to continue development, and also, Stan is helping us with the A24 port, so we are receiving plenty of support and updates for our modding project.
