r584 test notes

• Bug: Extractors can stack on top of each other.
• Bug: Descend throwing intermittent null ref on client, suspect depth charge?
• Bug: Homing Projectile throwing null ref on client.
• Bug: Guard-position command fails on client only, after a while.
• Balance: Depth Charges needs to be more effective somehow. Too slow/Not enough damage?
• Balance: Might need more effective ways to kill small craft, esp interceptors.
• Idea: Put a timeout on claimed metal as well, it got pretty crowded at the end.
• Idea: After Base is destroyed, game over? Without income, fighting mostly futile.
• Idea: Perhaps putting base beacon on Surface Relay? Make very expensive.
