Close the game immediately after killing all the bots at the same time. If not, the leaderboard will burn into the display.
Fortunately my burn in vanished but it's dangerous.
It's fixed. No more flashing when the bots are dead. I'm very sorry about that, I had no idea fast flashing could burn screens!
Thank you! :)
Fortunately my burn in vanished but i'm glad i could report it early.
