Construction of conveyors and pipes.

This isn’t a bug, but could it be made smoother somehow? It’s the same situation with conveyors.

If you are trying to have the transports path their way through a more & more complicated space,
the path generation fro them will get slower & slower, because the game needs to figure-out
how to path around all of the obstacles. And having a quite developed save is not helping this either.

This might be just a performance problem that's not improvable anymore.
