Comment 6 for bug 1208130

Without the above referred fix:

I see both spectator action and desync error, latter also with two "normal" human players.

After applying the above referred fix:

I see neither problem.

I removed the buttons entirely from a spectator. The other option would have been to keep the buttons, but make them non-functional, in which case the spectator would have been able to see the user's preference in addition to seeing the list of soldiers present.
