[Psycho]

If u can give it a type= which will detect whether the cursor is over a building or no, then u can ged rid of that IE. If u add type=ForceShield to TogglePowerSpecial then it works with no error. but the annoying thing will happen is it'll also draw a force shield over the structure, offcourse the force shield effect will no work at enemy structure.

Also, to shut down enemy power with Toggle Power, add PowerToggle=yes to all power source building. Now when u click on a power source building, it'll stop functioning. Moreover u can shutdown enemy super structures by default with this SW
