Weapon Systems on player built stations downgraded with time

[Helian]

I built Steel Refinery with all three stages in Integrative URV Forge (campaign mode), with all weapon upgrades except two V Launchers. Right after the construction of the station there was 103 items in Weapon Systems. Of course i was delivering weapons in parts. After a while (don't know exactly how many) i see that my station have only 34 Weapon Systems. I can't repair station, can't upgrade it. Some turrets on the surface of the station show Construction Site instead of turret type.

Uploaded a video where you can see this bug:

Save file, version 1.30:

This save from russian version, so some text in Logbook, Mission manager, names of crew members and names of ships is missing in english version of the game.

Have this issue on plot Integrative URV Forge. In this zone i have Arms Tech Fab, which i built earlier than URV Forge, with exactly same issue. But now turrets on that station is somehow repaired itself, and Weapon Systems show a right number, and turrets on the surface of the station do not show Construction Site.
