As of the version 0.8.10, there’s a glitch which causes you to be signed out of your automatically created account through Steam. This guide will help you solve that issue.
 
 

Simple Fix

This is the simplest method we know of as of now, and should work every time.
 
 
1. Close the game if it’s open.
 

 
 
2. Go to your game files (C:\Users\(YOUR USER HERE)\AppData\LocalLow\Studio Kit\Wee Tanks)
 
 

 
 
3. Delete the user_credentials file.
 

 
 
4. Reopen the game *using Steam*
 
 

 
 
If you do not open the game using Steam, this will not work!
 
 
If you did these four steps correctly, you should automatically be signed back into your account, allowing you to save your progress. Mainly the marbles. And the Gary Companion. Yeah, actually, mainly Gary.
 
 
(Note : If when you reopen the game you still appear to be signed out, open the options menu, and then close it.)

I am not the one who discovered this fix, I just wanted to make it as easily accessible for the community so that newer players are less confused.
 
 
Special Thanks to the one and only Chooky, as they were a big help in solving this.
