Just spent the last 2 hours driving Cumberland to Shaw mine, get to the point where I have to attach the loco that leads down into Shaw mine. Walking down to it, and stupidly asks me if I want to give up control of the service. Usually I am aware it occasionally asks this but out of flinch I accidentally pressed yes to give up, (3rd time it asked me in the past 5 minutes), lost all of my points and a waste of my evening. There should be an option to disable this popup, or get rid of it entirely. Why would anyone want to give up a service unless they're sitting in a different train?
