oh ok I figured it out you have to be looking at the connection point in a certain angle till the higjhlight goes green and it is actually connected this is really tedious although, I hope keen fixes that asap!

I hit f10 double click and paste one module down then I do the same for a second different one but it will not allow them to attatch them the square around the second module goes red unless it is 1 block distance away then it will allow me to paste it but I cannot fill the gap with blocks.. The game physically will not allow me to paste them together is what i am saying. I hope its just a bug or something.

You have to paste them together. This is the easiest way but you can also use merge blocks, but I don't recommend it. Just paste one piece onto the others.

how do you connect these together ? I'm trying in creative mode but it wont let me put the peices together I'm lining them up properly and everything whats the deal?
