[7.60] BUG - Ship replacement not working correctly if gorup is completly destroyed

Problem:

I noticed a strange behavior with ship replacement enabled. It applies to stations and ships.
If all ships of a single group are destroyed, the ships are ordered correctly at the shipyard and fly to the station or ship.

But as soon as they arrive, the group they should have joined is being disbanded and the ships are now idling.
