Version 27.1, Took a break from 0AD, First game as Han in the map Ardennes Forest, I've beaten Iron Turtoise Very Hard(Mauryan-Random Behavior), around min 24 and I was max pop at min 20, there was some attack but its nothing compared to vanilla VH Petra. I've checked the replay and well... it had 15k food with little to no other resources(5-10 workers work on this) once reach T2 at min 10 and because of that its population was stunted at 81 because not enough resources or simply because the harrasment was not supposed to be and that from there I just stopped their economy like that. My recommendation, use civilians to mine stone and metal only to the max of 24 in batch of 3, because thats what I do as it only requires food. I'll go play more samples of 4 more and I'll edit this later, respond once I complete it.

Does Protectorate work on r28? Has anyone tried it? Please give me an answer. If it works, I will just fix Iron Tortoise and Economy Master by changing the dependency from 0ad 0.27.0 to 0ad, or if your machine has an IDE, just open the mod json file and edit it.

Another 3v3 match (3 Protectorate vs 3 Petra, Civ: Han, Liu Yi as Empire, Liu Zhuang and Liu Bao as vassals)  

Has anyone ever defeated Iron Tortoise or Economy Master? What do you think of them as formidable opponents?

So now that a did a new try, with zylis comands it worked fine. Now the next idea is to compile with machine specific Optimation ( Intel Skylake), to see how much this makes a difference. Where is the place to put the compile options?
