Thanks for the bug report! Some changes to the game master caused some node names to be set to the incorrect value, so it isn’t able to set the campaign to be completed.
A fix for this will be in the next unstable build.
Unfortunately, this will cause the orc war to have problems starting on your current save, because one of the requirements is for the goblin campaign to be complete. If you download the debugtools mod, you can trigger the campaign manually to skip the goblin campaign completion check. Open up the campaign browser:
Under orc_war click the words wait_to_start and then click Trigger Now on the window that pops up
Let me know if you have any questions!
