Likely related to events not firing after rewriting the ping code.

I've added in a patch to help with this though server list functionality is still a little unreliable such as when deleting servers.

This still may be present, but is a little faster and better in more recent versions.
The server list is due a rewrite, I'll keep this bug open until that happens.
