I hit a reproducible error in my game. I get the oops error message when searching the Isolated Village near Whenura Cleft. Interesting thing about this, is the game attempts to keep going if I ignore the message, though without audio. I finished searching the area and made a new save afterward. I think I can just continue on with that save just fine.
The crash report is too large for forum. See link for full report. Contains 3 crash dumps for same issue. DXDiag dump. Save file just before crash and a Microsoft Steps Recorder file showing screenshots and such of what lead up to error.

On a side note. I tried to use the forum's search to check if this was a duplicate but was prevented by the flood guard. Sorry if this is a duplicate.
On another side note, really enjoying the game.
