As further information this happens on both Directx versions 11 and 9, the difference being that in 9 the game actually crashes and Windows gives me the typical "The program has crashed" message, the game on the other hand does not communicate any error.

After posting this, i also went back and tested every single other trial instance and no error/issue occurs, it's only Akh Afah Amphitheatre that causes the issue and it does it invariably and always.
