В ReadMy к версии RAR 1.01 написано: "Since the RaR Barbarians are more than a small nuisance, it is also recommended to add the line NoAIPatrol=0 to your conquests.ini file (in the Conquests main folder). This will restore the PtW Barbarian behaviour. Note this will cause the AI to patrol its borders again, leading to lags on slower machines after the Ancient Era; for that reason, you can simply change the line to NoAIPatrol=1 once Barbarians are no longer important (usually around mid-Medieval)."

Если добавить параметр NoAIPatrol=0 в conquests.ini, поведение варваров в конквесте должно стать таким же, как в PtW.
