Small saveserver changes

[ArchangelWTF]

• Adds a saveguard to the current profile being saved to prevent it from being called again for a save if one is already underway, this is only ever possible in my testing to happen on certain race conditions where a user might quit the game at the same time as the server is saving, none the less it's better if this is only processed one-time
• Wraps current timed saves in a try-catch so that if one profile errors out during saving this does not completely stop the method from running.
