I decided to buy the White March part 1 today, but when I installed the expansion and loaded my previous saved game, I found that all of the quests (both quests that I was working on and quests that I had completed) were gone from my journal. This happens with any saved game that I load. I also can't start the White March quests when I talk to the steward, but when I start a dialogue with with her, there is a conversation option that reads: 'Missing 06_cv_steward 215.' Clicking on that leads to other missing dialogue options.
I've tried starting a new character, and the problem persists. When WM1 is uninstalled, the problem goes away.
I'm running the game on Ubuntu 16.04. I downloaded the game from gog.com.
Any thoughts on what I could do?
Thanks.
