I am playing through a campaign as Skarsnik with this and the Conquer Anywhere & Confederations mod and confederated with Wurrzag and noticed a strange bug. One of his traits is listed as [Hidden] and Savage orcs have more upkeep with him instead of less (i think its by 40%). Its possible this is due to the other mod or the two mods just not playing nice but its probably worth looking in to. He seems fine if I start a campaign as him but its possible that the bug only comes about later on or only when he is controled by the comp.
