Partner issue in Wendigrot Ruins. (Arcanum: Of Steamworks Magick Obscura)

I came to the ruins, examined them, everything seems to be fine. He went with his companions into the opening and found himself in front of the altar of the supreme god Arcanum. Everything seems to be nothing, but ...
My partner was Sogg, Gar, Virgil, Raven and Perrian, as soon as I was in front of the altar, I notice ...
Virgil is gone. In place of Perrian's icon, a blue square flaunts. Raven refuses to move. But most importantly, instead of Virgil, I have a new companion - the Wall. I try to get them all to leave, but the Wall never fails. And it would seem, what is the problem?
When I am about to leave the location, the game starts to crash for me. In any case. Tell me how you can solve this problem? It's just that the old safe is far away, and you don't want to go through Tulla's puzzles again.
