Kerbal Space Program

(Attached quicksave file).

A satellite repair contract from the quicksave refuses to complete because it claims I did not repair the Communicatron 16 antenna when I absolutely did. This is the contract in question from the attached save file:

            CONTRACT
            {
                guid = c072ab91-3b9b-47e6-8dde-9636ff7230a3
                type = VesselRepairContract

I investigated in the save file and I see something very suspicious.
This contract claims the the part I need to repair is the following one:

                PARAM
                {
                    name = RepairPartParameter
                    state = Incomplete
                    values = 0,0,0,0,0
                    bodyName = Kerbin
                    partName = longAntenna
                    partPersistentId = 1509972433
                    vesselPersistentId = 3819982714
                }

What I find suspicious about this is that while a part with persistentId=1509972433 does exist in the save file, it is NOT on a vessel with persistentId=3819982714 as described by this contract parameter. It's on a vessel with persistentId=490346003 instead.

That older vessel, with persistentId=490346003, also coincidentally happens to be one that was spawned by this very same type of contract earlier in the game.

I suspect this: This type of contract only works right the first time it spawns a vessel of this specific design. The second time the same design of vessel is spawned by a second instance of this contract, it won't complete because it's using a part ID that's on the vessel the first contract spawned, not the new second vessel.
