Stage related requests cause EOFError

[Rhahi]

Two stage related requests, specifically

• KRPC.Interface.SpaceCenter.Helpers.Stage
• KRPC.Interface.SpaceCenter.Helpers.CurrentStage

Cause EOFError. (There may be more)

import KRPC.Interface.SpaceCenter.RemoteTypes as SCR
import KRPC.Interface.SpaceCenter.Helpers as SCH

conn = kerbal_connect("Test", "127.0.0.1")
ves = conn |> SCR.SpaceCenter |> SCH.ActiveVessel
parts = ves |> SCH.Parts |> SCH.All
SCH.Stage(parts[1])

Output

ERROR: EOFError: read end of file

Unfortunately there is not much information other than EOFError.
Note that this error may break the connection due to current semaphore implementation, so I suggest patching in a try-finally block on SendBiMessage while testing.
