I updated to the lastest stable build not too long ago and had to update NWJS. so i can't revert. Unless there's a way to do so. My game just released on steam and the bug is keeping people from being able to close the game properly. :/
Some people might not realize at all and then they can issue a refund because of the in-game timer going on in the background. My project is pretty big so maybe that has something to do with it.
