Every elevator I have entered so far has stopped working at some point leaving me trapped.

The first was in the Troubled Waters quest when I had reactivated all the machines. After trying multiple times I realised I should just exit the way I came in.

Now I am doing the quest to save Rex in Trinity Tower and once again the elevator fails to bring me to my destination once Fist stops speaking. This is very disappointing. People always say that Bethesda glitches are funny and acceptable but I fail to see how now.]
