EAB v15.0.xx
A NASS ship docked to one of my ships which was already docked at my residence. My ship was docked to a secondary airlock that was floating in space, but had planned construction leading to it. The secondary airlock was real and installed on my residence.
Also this is a good save for looking at performance (almost completely unplayable slide show / character movement tics seem to happen only every 1-2 seconds) and NPCs spawning into a residence. There were about 18 of them when I last counted, but it looks like some have died.
I've posted this as a new bug because my save is fairly complicated. Three player owned ships plus a residence. And I didn't see this exact NASS docking issue in another thread unless I missed it.
