Theres a wierd thing that happenes when you make a level and you put part of a goal box/circle inside of the workplace and theres part out of the workplace. When you do this, when trying to beat your level, if you grab the part of the goal box/circle thats in the workplace, you can move it where ever you want. But once you drop it you can't get it back.
also, pretend that the workplace's faces on the top, bottom, left , and right, all kept going the direction they are in. you can only put them in those spots, and not in the corners. Thats not really worded very well but i hope you get the point.
Take this, http://FantasticContraption.com/?levelId=1171 in this you see 4 goal box/circles. 1 circle is completely on the outside, 1 box is completely on the inside, 1 box and 1 circle are halfway. you can take the halfway in goals and move them inside the goal box. like so: http://FantasticContraption.com/?designId=111833
why can you do this?
