I’ve done 2 playthroughs of the game ever since I’ve had my 3080Ti build and been all over that specific area near Pronghorn Ranch and never have I once noticed this bug before this most recent patch, but like you, I’ve also tried downloading older builds of the game but via the Steam Console Depot instead, and it also occurs on those older builds too, which I’m baffled by! I’ve recently changed my game settings to use DirectX12 API over VulkanAPI, and it seems that while it still occurs when using DX12, it happens wayyy less often over Vulkan! Maybe it could be an Ampere Driver issue; it's just strange how it only happens at that one specific spot!
