For some reason it doesn't work anymore, it doesn't shoot anything, the targeting rays repeat themselves over and over again in whatever direction you look, nothing fixes the annoying targeting rays, even dropping the Euclid C-Finder doesn't work, waiting doesn't work, loading an autosave doesn't work. So you basically unless you load your last save game before you used the Euclid C-Finder you would have to go through the rest of the game with those annoying targeting rays repeating themselves! how many people have experienced this and did they experience it before the patch?

I found a video of it to show you what the problem looks like.

except it doesn't matter if you press it or not the targeting rays repeat themselves without pressing anything.
