No, clicking anywhere doesn't help. I got out by alt f4ing the game and loading the auto save. There is a very tiny strip of land you can walk on up on the mountain. It's very jerky to walk up there and sometimes the bandits spawn there. Which seems to confuse them because the "patrols around base" are all over the place. In any case it seems like there either shouldn't be a way to get on the mountain or the area to walk should be more then a strip with glitchy pathing.
