Game is set to 640x480 whenever I log in.

As the title says,  every time I logged in, the game would set to 640x480 no matter what and the game wont let me save my graphic settings for some reason even I pressed apply mutliple times. (Everything's on ultra and 1920x1080 with the latest game update installed.)

Before 0.29 or the Character visual overhaul, it worked fine but it's getting annoying and could affect my gameplay experience if the problem persist. 

After replicating the issue and the solution, I managed to fix it permanently. (**However, I cant guarantee it will work for anyone's case though. )

Here's what I did;

• Set desired resolution (Eg. 1920x1080)
• Do not press apply.
• Switch to "borderless fullscreen" then press apply. 
• I noticed the "apply" button is gone.
• Exit and restart the game to see if the changes is made.

There's another method but "this is a low chance rate";

• Set the resolution to 640x480 and apply.
• Change it to 1920x1080 but press cancel instead. It will visually revert back to the lowest resolution. (640x480)
• Select 1920x1080 again BUT switch to "borderless fullscreen" instead.
• Press apply.
• You'll notice the "apply" button is gone.
• Exit and restart the game to see if the changes is made.

After that, I dont dare to touch or change any settings ever again as it will reoccured and I have to do the procress all over again.
