Issue I got when starting up the game

[BravoAlpha101st]

Exception occured while loading contract 'ExplorationPlus.ExplorationPlus-FlyBy':
System.ArgumentException: 'Valentine' is not a valid CelestialBody.
at ContractConfigurator.ConfigNodeUtil.ParseCelestialBodyValue (System.String celestialName) [0x00046] in :0

I believe this error was caused by Extrasolar after I removed the mod because I kept getting contracts to explorer Valentine BEFORE any other planet.
