Yeah, I know. I did a system restart and now the gantry moves, but stops short of the Atlas. Also noted that the gantry carriages (the silver/gray things that contained the wheels the gantry rolled along the tracks on) do not move. The gantry moves toward the Atlas, but the carriages stay at the parked position at the far end of the tracks.
Historically, the gantry lined up with the Atlas and in fact surrounded it at the start. The begining of the sequence should have the gantry at the spacecraft, not the parked position. To be completely accurate, the animation would need to contain 2 moves...the first translating backward off the 2 blue/gray supports along the sides of the pad and onto the tracks, and the second translating to the right along the tracks to the "parked" position. I don't know if this is possible though. If not, getting it to line up properly with the Atlas would certainly be good enough.
The umbilical should also disconnect at first motion of the booster. Again, I don't know if this is even possible.
If you think this can be corrected, let me know as I noticed I forgot the operator's cab on the gantry and would like to add it if this can all be sorted out.
