@lumpthing: I just did a minor work on the leaders threshold when it comes to open borders agreement. They would be more reserved now: Os-Gabella shouldn't open her borders to Arendel Phaedra (the latter being good and the former now requiring pleased or above). It should slow down disciples spamming. However, if, in said case, Arendel opens with Jonas who opens with Os-Gabella, if the elf spread her mean disciples to Jonas, he would certainly do the same to Os-Gabella.
I have included a modified version of the Orbis editor in which I red-colored the parts that I modified (only in Leaders tab and OpenBorders line... I should have colored all others red cells back to blue but I forgot

). For installing, simply extracts in your Orbis folder. It should ask to overwrite, choose yes.
I think the ReligiousWeights need reworking too.
I also think that RoK shouldn't alter alignment. Am I missing some lore that make this utter nonsense?
I also also think, on another issue, that it may be nice to mod a bit those minor leaders. When looking (quickly) through them, I saw that they are many things in common with major leaders, like clones.
