It usually happens when player jumps up from the water or looking up at the arch's ceiling (or maybe looking on the sky from above the arch). Then game crashes saying:

1) It happens with Vavoom 1.19 as well
2) it happens only with Software renderer. I am not quite in knowledge of how these video things work, but maybe this only depend on specific machine?
