For some reason having a higher than 60 fps display running at more than 60 fps can be (one of) the causes for an infinite loop of your character walking towards, but never reaching, a terminal or power armor. By alt-tab ing out of fallout and changing your screens refresh rate you can solve this issue without losing progress.
