I don't use anything but CP/CBP.
How did you know? Now that you speak of it, yeah, the error happened right about when I got a monopoly on Cocoa.
The error was related to a lua function that is called when you have a monpoly. Your logs help. I'll see what I can do. In the meantime, you can continue the save, most likely, by using the firetuner or IGE to remove some cocoa plantations. not ideal, but seems there's a bug in the lua.
