Diplomacy stopped working

[dallago_br 0]

For some reason, now my relationship with every country (with some exceptions) in the world is 0 even though I send them insults or diplomats, so I can't neither send someone an ultimatum nor make an alliance. Maybe the fact that I reunited the roman empire in the 9th century and no one in europe can defeat me has something to do with this.

Me paso igual... Pero se quitó con el tiempo. 

Lo malo es que las partidas guardadas no me cargan y se inician otras nuevas.
