bug while attempting to remove ai

[Etheral]

was attempting to setup a game and accidentally inserted a bot when I thought I was typing.
attempted to kick the bot to remove it resulting in the game crashing. no game id was recorded.

At present, kicking people or having people leave generally tends to result in crashes.

The game attempted to cast me from Spectator to Player once after a bot got kicked during game setup, and crashed because it couldn't actually *do* that. (There isn't a log to link to AFAIK because the game never started; actually, the host crashed too)
