F10 Mission Command failure upon reloading MP mission

Reloading a multiplayer mission causes F10 mission commands to no longer work.

function ShowA()
trigger.action.outText("A", 1)
missionCommands.removeItem({"Show A"})
missionCommands.addCommand("Show B", nil, ShowB)
end

function ShowB()
trigger.action.outText("B", 1)
missionCommands.removeItem({"Show B"})
missionCommands.addCommand("Show A", nil, ShowA)
end	

ShowA()

Reproduction:

-Launch attached test mission as a host. The mission includes the script above (generates F10 mission commands).

-Enter client aircraft, unpause the mission.

-Cycle through text output "A" and "B" using F10 mission commands (works as expected).

-Reload the mission using "SELECT MIS." directly from the running mission.

-Repeat from step 1: F10 mission commands are no longer working, no text is put out.

I'll look into it. Do you know if it does the same thing with trigger based F10 commands?

Bump.

Cost me a perfectly good mission progress in the Guardians of the Caucasus campaign, and probably happens to a lot more people. Any solution in sight?
