I'm not sure exactly why this mob is at Cad Nua, but Marshal Forwyn still talks about Lord Gathbyn's army growing even though he is dead already.

Hey Jotra,

 

Did you participate in the beta by any chance? Do you have a save before you completed battle of yenwood? 

Checked, but didn't have any relevant saves from before the battle. Also yes I participated in the beta.

Hey Jotra,

 

I have written up a bug and added it to our database. Hopefully we can figure out what the cause of it could be. 

 

Thanks!

I have experienced something similar since receiving the quest "The Battle of Yenwood Field".

 

I got news that my stronghold would be attacked in some days and as I was 'at home', I decided to defend the stronghold manually. After I defeated the attackers, there was suddenly this mob in front of the stronghold with Marshal Forwyn in front of them talking about "The Battle of Yenwood Field". As I had not finished the quest by then, I chose the conversation options to start the battle which I won. 

 

When I returned to my stronghold though, the mob and Marshal Forwyn were still there outside the stronghold and I still got the conversation option to start the battle. Out of curiosity I chose that option and again got the texts for "The Battle of Yenwood Field" though there were no more enemies on the battlefield after clicking through the texts.

 

I used a save with which I lost several ingame days of play time (and thus, the quest was no longer completed) and when I received the message again that my stronghold would be attacked, I chose the "defeat automatically" option. After successfully defending my stronghold this way, there was no mob and Marshal standing in front of the stronghold. The next time, I received news of incoming invaders, I had the same results: Defeating the enemies manually resulted in a mob standing in front of my stronghold whereas defeating the enemies automatically did not affect "The Battle of Yenwood Field" quest in any way. BTW I have not completed the quest by now.

I had this written up in its own thread, and then a bit of Deja Vu hit me and I searched the forums.  I guess I previously read about it.  Anyhow...

 

I already completed The Battle of Yenwood Field (see screenshot) a while back, but Lord Gathbin seems to be alive once again after I manually resolved the Cutthroat bandit issue at the Stronghold.  At least, that's what Marshal Forwyn seems to be telling me by reminding me about the army I need to deal with soon.  Also, there's a reappearance of the angry mob of farmers/merchants which Lord Gathbin seems to have recreated after I paid them off quite handsomely for their trouble some time ago.  However, I can't talk to the mob.

 

Here's the saved game before I began the fight with the bandits:

If you manually resolve the bandit battle using this saved game, you'll see the crowd and marshal afterwards.  I've done it twice and it happened both times.

 

I also see you asked for a saved game before The Battle of Yenwood Field, so here you go:

Hopefully my saved game hoarding has finally come in handy.  (Minor rant:  I do wish the saved games list loaded faster, though.  I have to move older files out of the game's directory so it doesn't take 3 minutes to bring the menu up.  This is on a Samsung 850 EVO SSD, to boot.)

I also have this. I think it also happened after manually resolving a battle.
