Glitches exist throughout the game. Here are some minor glitches. Most are graphic issues.
Current Minor Glitches[]
Black screen after battle/attacked base[]
This is a normally occurring glitch. once you find an attacked/or you got attacked you would see black in random parts of your base. This can be fixed by reloading the game.
Time mess up.[]
This is where when you use a big speed up (such as 2.5 day accelerator) the game may mess up. showing before when you did the speed up. This hasn't been fixed.
Massive Graphics[]
Many graphic mashups occur, this is extremely rare. I got it, but I did not record it. It looked like Red, green and blue combining and all other sorts of stuff. This can be fixed by reopening the browser. Reloading makes it worse.
