Unbalanced Trade Logic

[mad hadder]

Is there any mod that changes AI trade logic? Is that even possible or is it locked behind DLL? Asking because when my group plays multiplayer games with AI civs the trade logic gets abused and there is no way to police it. In particular making loans to the AI and using compound interest over the course of the game to end up with absurd yields per turn. Don’t get me wrong, it’s a fun strategy in single player, but it would greatly help our balance if we could dampen the amount that AIs would be willing to pay for a loan. Any suggestions would be appreciated!
