[6.0 KE] Unable to supply enough hull parts to build ship

[Admiral Sausage]

I have attempted to purchase a Shark from the Boron shipyard in Great Reef. Since they are severly short of resources at the moment, I chose the minimum loadout, but with full crew. This still required me to supply thousands of hull parts, among other things, which I eventually managed. The ship never starts building though, because hull parts mysteriously disappear.

Here's a save game right before it happens: https://mrevil.asvachin.com/temp/x4/sha ... ave.xml.gz

The shipyard has been scanned enough that you can look at its stock, and see that it contains 18790 hull parts. Only 10 short of enough to build a Shark! This can be verified by opening the buy ship screen, and seeing that it says it's 10 hull parts short (and nothing else).

The ship GGI-969 is about to land on the station to deliver enough hull parts to fulfill the requirement. If you look at the station again immediately after it has unloaded its wares, the amount of hull parts does indeed exceed 18800, and it no longer says it's 10 short. However, a few seconds after that, the number of hull parts in the station goes down by a few thousand, and it will then say that it's 3713 short again.

This is the third time in a row that this has happened (that I noticed). There is only one ship in the queue (mine), no station construction in progress, and no pirates around, so I can't see where the hull parts are going.
