--UPDATE----
Bug has been fixed with recent Hotfix. All logging in should work fine now for all players.

Pretty sure I just found the bug, like 2 min after posting this...
The bug is preventing new players from logging in. If you created your account prior to the last patch then the bug isn't affecting you. This bug has to do with the huge reduction in file size that the game got in the last patch.
Unfortunately this bug has to be fixed by a patch so I'm preparing the game to be patched right away. This means there might be some new features which I haven't been able to test properly that might come in which could be bad. Any sort of problems from things coming in earlier than intended will get fixed in time. Since new players can't even log in, fixing this bug takes priority.
So i'm preparing for a new patch to fix this problem which I will try to push out as soon as I can(maybe a few hours).
Again sorry about this guys.
