So i downloaded the game this morning through steam. On main menu, top left it shows your username which mine was AHappyTeddyBear. After a few hours it changed to AHappyTeddyBear (1). i thought nothing of it. 5mins later it changed to my steam id which was this a bunch of numbers. and it didnt let me change the display name back to my orgianl one. so i just changed it back to AHappyTeddyBear_, help?
