Game crashes when loading bm_c3a1b.bsp

Hi!

I have a curious problem. I have the typicall graphic problems with de purple an black texture, but a part of that, the game used to work perfectly.

The problem is that in the chapter FORGET ABOUT FREEMAN, when I have to climb the stairs to go to the surface, on the loading time, the game just stays eternally loading.

I’ve tried to load that part with the console, the map is bm_c3a1b, but it just doesn’t work. It works with all the other maps that I’ve tried. I can go
to the next map “lambda core” but if it’s possible, I don’t want a miss a part of the game.

Is there someone else with the same problem?

Any idea of what is happening?

Thank you
