Combat Disaster

All the bandits die because the ai is so unable to run combat I have had to try and correct almost every turn. The AI is applying advantage when it should be disadvantage, and disadvantage when it should be advantage. The ai is turning my allies in to enemies with them attacking me rather than defending their own work place from bandits. The ai is applying damage wrong. The ai is not responding correctly to my attempts to correct its behaviour. This combat must finish now with the death of every bandit,
