General
Added a 30 second wait time between logins from the same account to fix a variety of data corruption issues that could affect characters. If you try to log into the same account within the 30 second window, you will receive an error message stating the account is already in use.
Note: This will not have any impact on swapping characters.
My issue with this, as I read it, is that the only time that you would try to log back in within 30 seconds on the same character is when the game has kicked you for no reason while in a Trial or such. This change means that rather than being able to log straight back in, we will now enforce a delay on the whole group every time someone gets kicked by the game.
