Working with Bobbi No-Nose and Mel to do some tunneling. I'm pretty sure I'm near the last soft spot, but I can't Activate it by pressing E. Pressing E does nothing. The game recognizes that the cursor is in the right area to pop up the Activate message, so I'm obviously in the right place.

Unless I can get through this wall section, I can't proceed with the quest. And I can't really see just walking away to do something else until I find a fixit. So for now, the entire game is on Hold.

Anyone know a solution to this quandary?

I had this bug. Reloaded the autosave from when I entered the dig, redid quest. Worked fine.
