Cemetery of the Eternals

Not sure what is triggering it but I am getting an infinite loading screen occasionally when entering the cemetery of the eternals.

A separate window pops up and says

"Detected Corrupted Game Files"

"Usually this might be either caused by an overclocked CPU or by corrupted game files"

Then when I close it out and reopen it on steam it has to reverify my game files.

This has happened a few times now, and curious if there is anything I can do to give you more info or what I can do to prevent this? As far as I am aware I do not have an overclocked CPU. So something else must be happening.

Thanks :)
