HELPFULL GLITCH: This will allow you to place engi's on top of eachother or in positions that would normally be red, such as outside of the box. 1st you need to place your engi over an area where you would be able to place him normally. 2nd you need to right click. 3rd click on the desired area and wa-laa! you now have a engi where ever you want. Thumbs up if this helped you!
