[0.18.15] Copy and Paste train signals failing

[Lardbucket]

When copying and pasting train signals from a straight track to a diagonal track, the pasted (new) train signal on the diagonal track doesn't work.

I tested this by placing a horizontal train track with signals. Using the copy tool to copy the train signal, then paste tool on to a diagonal adjacent track. When a construction bot places the train signal it looks like the horizontal one and fails to work. See gif here: https://gph.is/g/a996KNA (hopefully it's high enough quality to help)

Yes, that is how blueprints work, if you do not want that do not use blueprints for it.
