Ore state/view is incorrect when switching between teams as a spectator

[ghost]

Issue Summary

Hi !

I don't know how to formulate this in proper english (feel free to rephrase everything in this issue if you get it), so :

Steps to reproduce

• Start a game as a spectator with two players/teams
• Use 1 and 2 keys to switch between players/teams while spectating
• Spectate player/team 1 and let it harvest some ore
• Press 2
• What you see is what player/team 1 knows about ore, not what player/team 2 knows
• Now press 1
• What you see is what player/team 2 knows about ore, not what player/team 1 knows

Not sure how to explain it : the spectator view shows the last ore state of the map known by the spectator, not the ore state known by the team actually spectated.

System Information
