Fuel harvester ship given conditional orders to unload 90% fuel at colony within 4 jumps if fuel tanks full. Placed into orbit around my home planet with nothing to do, and ran a day.
During advancing of time, the game reports an error 5, invalid procedure call. The first time, I looked at the fuel harvester task group and found no apparent changes; 100% fuel, no orders. Trying again another day, I got the error, but then I saw the group with "Unload 90% fuel" tasked. I ran a third day by and looked again at the task group. No error reported, the unload task is no longer on the task group's plotted moves, and it's still at 100% fuel.
I hadn't gotten this error before attempting this function, and it disappeared after I stopped trying to have my fuel harvester dump its fuel.
