I think that the LTC AI money cheat is reserved for when the AI has 2 or less provinces.And as you know,Scotland starts with 1 province,sooo...big money for them. .Well to solve the problem,you either execute the prisoners,reinforce your army,or take advantage of the money cheat and make them your vassals.Jong has this excellent guide on vassalage.He used the LTC mod on vh/vh.You'll probably want to read it.
