A One-time SOLUTION*cough* for me *cough* worked a few times*cough* 1. Click where "Snapshot Viewer" should be (or "Character Customization"). 2. Click the in-game back button.
Here are some pictures to make it easier to find:
The story of how I found this
One day, Sarruby was bored. Veeeery bored. To the point of playing Clickerheroes, a waiting game where you can click to make it go faster. Her tablet can barely handle any graphics more complex than that, sadly. She was so bored, she opened her favorite Attack on Titan game that wouldn't load on her computer (which was very strange, since it loaded on her brother's and friends' computers).
As she waited for Clickerheroes to progress, she decided to practice her clicking skills on the white screen and pretend there was a titan there. She clicked and clicked and -
GERDMARMIT WHAT TEH FERFER (ÒДÓױ)
the "Snapshot Viewer" opened. Unable to believe her luck, she hesitated before clicking the game's "Back" back button. But the video game Gods were looking down on her that day, for the game's "Back" button opened the home screen! And so Sarruby did a victory fist-pump and killed a titan for the first time in months as her poor tablet wheezed and overheated.
Then she restarted her computer, discovered that her trick no longer worked because nothing would load, wrote this, posted it twice in two different threads, prayed that the moderators wouldn't mind, and went to bed.
The End :-)
This only seemed to work a few times. Then my computer wouldn't even load the partial screen, instead giving me a blank white screen to look at (which I can change to gray with the "Snapshot Viewer" menu and then see a Colossal Titan silhouette by clicking where the back button would be).
If anyone wants more info about my PC's details, let me know. Also, does this work for other people? Does it work more than once? Is it actually a solution? I will edit it to be "not-solution" if it's actually not...
