New beta build! https://wiki.arcengames.com/index.php?title=AI_War_2:The_Great_Refactor#Beta_3.701_Natural_Object_Order
This one is just bugfixes, as you might expect. I also made something like 4 hours of video tutorials on how to mod the game and how to use a variety of the code, which you can check out if you're into that sort of thing. The goal of that was to help ease the transition for existing modders into the new framework.
The number of bugs that people found were not overwhelming in number, which is nice, but I think at least part of that was because the ones that were found were severe enough to prevent too much testing. Ironically, most of those really severe bugs were just a few small things that were pretty easy to fix, so... well, that's a good thing.
The really big culprit was that I had allowed NaturalObject (aka no ownership) units to be in any order, rather than always being the 0th faction in the list, and that caused all sorts of crazy bugs if you happened to have it out of position 0 in your new save. If it was in position 0, then a lot of those same things were fine.
Other bugs included a few xml typos, a couple of years-old bugs that just became relevant but were not new, and some places where I had switched something to a new more efficient format, but the old format would throw an error if it was still called, and there were still some lingering calls to them.
All in all, so far none of the bugs were really very time consuming to fix, but as noted they were severe enough to really prevent deep testing by very many people. Hopefully this build is a lot more straightforward for people to test further with.
Thank you for the help with testing!
Enjoy!
