...no scratch that it just crashed in the midst of combat with a boar!

Same here. The game crashes started a couple weeks ago. I thought perhaps I needed to update my NVIDIA driver, but doing that actually made the problem WORSE. Now I can't play for more than 15 minutes without a crash.
The problem seems to arise during cutscenes or when talking to an NPC. During the normal gameplay I'm not aware of any crashes.
I have an NVIDIA RTX 2070 Max Q.

@netspook Thanks. I was so zoomed-in I didn't notice the level 20 areas! Cool.

^Not Londinium, I meant Lincolnshire. (Forum won't let me edit even though it's less than 10 minutes since I posted.)
I already spent my resources upgrading the stables after the forge; I didn't know we'd be required to upgrade the Hidden Ones bureau, so until I get new supplies via a raid I can't progress.

I've been doing a lot of side quests and exploring besides just following the main story.
But now I'm in England and going on my second raid with player's power at 23 and keep getting one-shotted by the soldiers there.
Come to find that this, the nearest monastery (Londinium) is rated Power 160??
How are we supposed to have gotten so high so fast?
Confused. As I say, I've been doing a lot of side quests, so,....?
Thanks.
