I can't load in to Rostok (Great Metal Factory) in Lost Alpha.

Playing on the latest version (1.4007+ DC) and other saves work entirely fine, but Rostok makes me crash no matter what. I just can't save, shoot, move, do anything whatsoever in Rostok. I even ran it in compatibility mode for Vista SP2, still nothing. I just can't play. I have the amd gpu fix installed, no frame gen, nothing.
