Given:
1) Shipyard
2) Ship design with few docked entities
Action:
Used "Test" order from shipyard computer
Result:
After getting inside of test-ship found out few docked modules are missing, despite them being intact before, in the design. After leaving test sector i've noticed those parts floating in the shipyard, completely with their "SY_TEST" signatures, while also looking like a fully constructed ship, without "holographic" effects.
The only differences from "real" ship - i was unable to move them, delete them, pilot them or anything else.
Also, because of those things being around shipyard anchor i was unable to load designs again - every time game showed me a message about something being in the way.
Eye-witness (friend of mine) says those parts appeared right after i was teleported to test sector.
