In Imperial Welryn area, after getting closer to entrance into Great College, everything on screen except few UI elements turns black.
everything keeps going on, so monsters attack etc
and it can even switch back to normal view and then back to black again while moving around a bit (seems random/erratic, did not found more specific area)
When this happen entering the Great College results in game crashing and losing all progress in last session.
