I've recently noticed that the traders' corners at my HQ have begun to disappear. To be clear, this refers to the shops in their entirety, not the NPCs at the shops. This apparently started after I added a wharf and sadly seems to be gradually getting worse. Also, I have no mods installed, not now or ever.
Originally, my HQ had eight (8) traders' corners in total, stemming from five 8M docks, two 3M6S docks, and one 1M6S dock. In short, the station had eight docks with one traders' corner apiece. Pretty straightforward. This was helpful for gathering wares (seminars, fine meal ingredients, EMP materials, etc.) in a pinch whenever needed.
After a wharf was completed at the same station, all of the 8M docks ceased to have their traders' corners. Oddly enough, the ship dealership spawned at one of the 3M6S docks instead of the wharf. But the wharf itself generated two new traders' corners. The new total count of traders' corners fell to five (5), three at the xM6S docks and two at the wharf.
However, more recently, the ship dealership has been moved to the wharf, replacing one of the traders' corners previously located there without creating any replacement elsewhere. This reduced the total count further down to four (4), one per xM6S dock and wharf.
Lastly, during some of my most recent visits, the wharf (ship fabrication bay) offered no traders' corner whatsoever, resulting in only three (3) available shops at the HQ. Unfortunately, I don't have a screenshot as I intended to investigate further but have not been able to reproduce that state yet.
I'm concerned that this trend will continue and result in all the traders' corners disappearing. Is there some known conflict or issue regarding traders' corners and build modules? Is there any way to recover the lost traders' corners and prevent this shuffling and disappearing?
