If anyone notices any bugs like that, a server restart is only a PM away. It's far better to PM than chat, since I get a mail whenever someone sends me a PM, while chats are likely to go ignored for long periods of time.
EDIT: And unless I misunderstood Chris post, it's not the age of the world itself that causes the problems, but rather the uptime of the server (for instance, a bug that is triggered in hour one of the server might still cause problems in hour ten, unless it's been restarted).
