Bug: Script error when talking with lord
Hi, not sure where the best place to do this is, but I'm getting a bug when I try to convince a lord to rebel against his king. After I ask hin about his king, the option to tell him to join me generates a script error, and the dialogue options going forward get weird. Should I upload my save somewhere to look at?

Cheers
