I'm doing the Cartagena assault, and once I finally destroy the cannon, surviving the 6 enemy waves, each time after the shop menu the game just crashes to desktop.
Happened twice in a row. And the game reloads me back in the same cannon checkpoint to do it all over. I don't have the patience to go through that again tonight, that fight is exhausting.

Ryzen 7 3700X, RTX 4060, 32 GB of RAM. My specs shouldn't be the problem here.

Hopefully, there's a fix for this. Been generally enjoying my time with the game up to this point.

Update: I was able to beat the level. However, since the ship fight that follows, I continue getting the "save failed"
message.

I can beat the ship battle, but then in the subsequent mission, it's constant "save failed" and when I quit tot he menu and try to reload, I get sent back to the Battle of Cartagena ship fight.
