EDIT: Was my L freighter Selene trying to dock at a station that has no L dock. I told it to deliver stuff not only to the build storage but also the station since it was one way and didn't thought about that..
[wrong]My thinking is that comes from 2 miners I just bought to do mining for my HQ station (right click role). I think they were already subordinates. But now they are in the normal list. I already tried to cancel all orders, but that didn't change the problem.
(The 2 in Pious Mists, I marked one wrongly in the screen)
I had both selected when I clicked on the HQ to give the mine for station command, I guess that caused the problem. [/wrong]
