The world disappears

Reesh

Hello, a new problem found looking for the alien power plant, I would like to know if someone else happens to him and if he has solved it.

When I go down to the alien station of disease research, I continue down to the magma pools, towards the alien energy plant. There comes a moment, in which it seems that I leave the cave, but I disappear all the graphics, I remain floating with my cyclops in the void, I get to the point and there is nothing.

Any suggestions ??
