This is just minor, but today when LL closed the server, the game actually closed within 1 second. Normally when i walk into a tavern/inn it takes 15 seconds before it closes by itself. It is annoying when quickly logging on ur other character or when u wanna close it quickly. Is this possible to change it so it closes faster? or is it client side?

If you use dxwnd, there is an option to make it terminate the game fully once u hit the X button(after u run into a tavern of course), but it results in hotkey changes u did in that session to not save, possibly other issues too.

Unless the server crashes (or is shut down) the close speed is managed by the client.
I am not sure what it does in that time, possibly closing connections and saving data files but not sure as I have never looked.
