i think you should be able to reverse this. Open your save file in notepad and search for:
{\"rid\":2660,\"type\":{\"class\":\"ValueBool\",\"ns\":\"GameCreator.Runtime.Variables\",\"asm\":\"GameCreator.Runtime.Core\"},\"data\":{\"m_Breakpoint\":false,\"m_IsEnabled\":true,\"m_Value\":true}}
and instead change it into:
{\"rid\":2660,\"type\":{\"class\":\"ValueBool\",\"ns\":\"GameCreator.Runtime.Variables\",\"asm\":\"GameCreator.Runtime.Core\"},\"data\":{\"m_Breakpoint\":false,\"m_IsEnabled\":true,\"m_Value\":false}}
(you only need to change the "m_Value\" into false)
