The patch looks like it does what it says it does.  However I don't
think this is a sufficient fix.  Because if the player doesn't set a
goal then at the end of the turn the server will pick a tech for him to
research.  And this probably also causes the bulbs to be lost.  So I
think the bug needs to be fixed "at the source".
