I'm doing the alien quest where I have to destroy the 3 generators before I do the space walk.

Well, I activated the electrical switch in the robot assembly, and set it to disrupt the conveyer belt. The problem is, it's supposed to blow a hole in the wall but it didn't. I try to activate it again and again but nothing happens. The "activate electrical panel" writing shows up but it won't let me activate it.

Anyone know if this is a known glitch?

I had no problems with the other 2 generators in the Cryolab or the Hangar.

Yes I believe it is a known glitch because I've experienced it first-hand myself.

Unfortunately, if your are not on the PC, I know of know way to get around it aside from reloading a previous save (which is what I had to do). Otherwise you could probably just use console commands to fix it.

Ah, thanks for the info.

I tried fat-manning a hole in the wall but that didn't work

Looks like a previous save it is
