My suggestion would be that the loading screen let you know if you've been disconnected or if it's not actually doing anything.
Right now it'll let you wait indefinitely long after it's failed to load or connect.
On top of this, it can't be cancelled or quit. You have to control+alt+delete to close the game down and retry.
My suggestion would be to give it an optional "cancel" button that shows up if the connection drops or a period of time elapses. It could either dump you back to login, or ideally, whatever location you just came from. Either is better than being left permanently in limbo.
Also, as has been mentioned, you can't even submit a bug report from the load screen. Perhaps that could be added to make sure devs become aware of things like this?
I'll just add that my character is also permanently stuck loading sirius sector each time i log in with him, and there's currently no way to avoid or stop it. Definitiely something that needs to be urgently looked into.
