Random crash on loading 'world' caravan screen.

[vastowen456]

When I load up this screen, sometimes the world's background (the land/water) doesnt load, it's just empty, but the settlement nodes stay and there's still functionality. Also there's like a 50/50 chance it insta crashes. Then when I form a caravan, when I click the select route button there's a chance it crashes there. And if I go through all this successfully and the caravan moves to leave, then I gotta save quick because a crash is incoming momentarily. Quitting to the main screen doesn't help, if I try to load back into the world it says there's an error loading it, so I gotta quit to OS and reload.
I have a lot of logs, and I'm not sure if having multiple helps, so here's a few:
