Again in the 9:11 pm save from the online game, you can see the ship 1169,1042 waiting for another 5545 hours for load, although no wait for load has been set.
Hmm - have you tried advancing the schedule manually once and seeing whether the problem ever recurs? I wonder whether this might be a transient problem connected to the fixing of a bug relating to docks.
i'll see if it happens again then :)
