Yeah this happens at several points, and making the AI buddy useless in combat is probably one of the dumbest things the developers did in this game. I try to play this game to relax and unwind and instead I am about ready to pull my hair out and throw my controller. It's kind of funny or sad, depending on how you want to look at it. Are there going to be many more situations like this? I am not even sure it is a thing that needs to be built to progress, but the simple fact that I can not build it due to the fact of poor friendly AI or purposely built that way so they are worthless, is really starting to grate on my nerves. If I clear the screen of all enemies more spawn and stop my progress of building just in the nick of time. If I purposely stop so I can block or dodge, it resets back to zero. So essentially I kill all or try and save one, but that bastard keeps shooting me and it resets the building back to zero. Luke can not do it, apparently it needs a Jedi's 'touch'. There is a part where you can build 'something', but raiders keep spawning and sliding down the hill just in time to stop your progress of building. I am more familiar with the original movies, so basically IV, V and VI and on the very second mission of IV there are sand raiders or something.
