Upgrade populates tech tree with duplicate values

[GarrettKajmowicz]

I have a career-mode game I started in 1.0.5. Tonight I upgraded to 1.1. When I go to look at the tech tree, I noticed duplicate items listed. Upon exiting the game, I looked in my saved game and noticed contents like this:

Under the section 

SCENARIO
        {
                name = ResearchAndDevelopment
                scene = 7, 8, 5, 6
                sci = 0.9976196

there was:

                Tech
                {
                        id = flightControl
                        state = Available
                        cost = 45
                        part = R8winglet
                        part = sasModule
                        part = Mark2Cockpit
                        part = winglet3
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                        part = Mark2Cockpit
                }
This was only duplicated a handful of times. Other sections had hundreds of duplications. This was shown in the tech tree as duplicated items as well.

Other items duplicated elsewhere include: Mark1Cockpit, SmallGearBay, nacelleBody, JetEngine, shockConeIntake, structuralPylon, radialEngineBody, shockConeIntake, turboFanEngine. I expect items to only show up in the tech tree once (or possibly twice if they were moved between versions and my overwrite of the install didn't delete the old versions).
