Hi Hawkeye,
Thanks, yeah it should have said no engines.
As this is a learning game, I designed the barge and the tug, then magiced them to appear.
When I go into the Ships window, and select the Barge (That which has no engines, but does have a tractor), I can see shipyards in the drop down but not the tug.
If I put the Tug and Barge in a task force and move them away from the shipyard (at 1km/s), I still can't see the Tug, in the Barge's Miscellaneous window.
Also and not wanting to expand this too much, most times when I open the F6 window I get a bunch of errors, sometimes 2 in a row, sometimes 6, sometimes an infinite loops worth.
Could my tractors be related to a problem with my install of Aurora.
Similarly if I open the Galaxy Map view it gives me a bunch of errors about missing image files, where would I get all the ancilliary files to stop all these errors?
