Kerbal Space Program

This is the module I am replacing stock control surface modules with:
https://github.com/Boris-Barboris/AtmosphereAutopilot/blob/master/AtmosphereAutopilot/SyncModuleControlSurface.cs#L30

Currently the game throws nullrefs all over the place of the following form:

EXC 03:26:54.928] NullReferenceException: Object reference not set to an instance of an object
