TwoDie AuthorTrying to find out how to make when ordering to build building for builder that it wouldnt deselect choosed building to build. You select workers, click on build supply depot and you order where to build supply depots without holding shift key while you placing, making build queue.
Any chance of doing so? Maybe triggers may help in anyway ?
Edit: What makes SCV slide when building a building?
