Struts

[Engineer(ish)]

When I click to connect an anchored strut from one object to another, the anchor moves from the part I put it on originally.

As this isn't a tech support thing, but more of a Gameplay question (I think), It has been moved.

When you have a placed strut, and then click on it again, it automatically picks up both ends of the strut, and you will have to re-place the anchor side again before placing the second end.

Also, for a strut to connect properly, there has to be a direct line between the two ends that does not intersect any other part. If the strut intersects something it's considered "illegal" and one of the ends will be moved automatically.
