I tried to get the tracking device and it exploded. I left and when I got back, it was gone. How do I get it now? Thanks

Hi VRMpls2,

If you check the messages on your PDA, Sophia will have given you another location where a tracking device has been left.

Save your game just before you go to this location. Then, if you're unable to find the device in time, you can reload and try again, checking different areas of the scene.
