The ACP is still working with the ACP.ini file in the Documents folder (not the AC one, rather the main Documents one). You have to load an ACP saved game, then open ACP.ini and change the parameters, this takes effect immediately and will be saved, you even have the "Animus Control Panel settings have been saved" prompt in connect+
That would be better with the menu, but they removed it, although they recently forwarded the requests of several players to reintegrate it.
SunBeam, do you think it would be possible to have a script to re-initialize chests and ptolemaic/romans camps objectives? There is a class of ptolemaic soldier that acts as commandant of the largest camps (they are huge with a large axe), but when you beat them once, they disappear. If it was possible to reinitialize the objectives for those camps, this would be great. There is a funny "bug" about them: If you set romans to ptolemaic relations to "enemy", then in some places you have both those ptolemaic and romans (such as chersonesos fort, or prince's wall in the hidden ones DLC), and so those ptolemaic commandants actually fight the romans
Since they have a lot of health bar, this is very fun to watch. Sadly, once you kill them, or, randomly, the romans kill them, they disappear.
