Steve -
I've been playing around with 4.0b a little, just to try to stay current with what is in the latest versions, and I noticed a bug. I set up a cargo run for a group of cargo ships from my home world to a planet orbiting a distant binary companion star, using lagrange point jump points. When I set up the first round-trip, everything was fine. The trip time displayed what I felt was a reasonable amount of time for the round trip at that point (10 days or so). Then I entered a "3" in the repeat box and hit the repeat button so that my cargo group would make four round trips. Aurora immediately threw and error related to calculating the trip time and after clearing an error showed a trip time Aurora showed a trip time in the hundreds of thousands of days.
I double checked, and there were only four round trips displayed in the orders list. I then checked the orders sequence, to see if one of the in-system jumps was left out, but everything appeared to be right, so I decided to let the fleet follow its orders and see what happened. The fleet made its first round trip in ten days, as the original orders predicted that it would, but then, on the first leg of the second trip, it missed the LP jump point and kept sailing straight on towards the distant companion star through normal space.
It appears that when the orders are replicated by the "Repeat" button, something relating to the LP's is left out, disabling that particular function.
