It seems to me you have to put the data and logs folder in mods/ebii directly.
And thanks for all your videos Sarkiss, it is nicely done and I really appreciate the historical content you share with them.
It reminds of
videos of reenacted ancient battles, done with EB1, that I watched some years ago. Although the commentary (in french) was often vague, what was cool was that the battles were done in multiplayer. It allowed the guys to make a reenactment of the battles, and their sequence of events, backed on the writings of ancien historians. I don't know, maybe it can inspire you ?
