I could recreate this bug, but cannot explain why this exactly happens. This bug seems to be related to higher scores with at least 5 digits. Someone suspected this to be intended, but it’s not! I’m eager to give you pleasure and a nice user experience, unhappy bothered customers would simply stop playing, this is pretty sure not my intension. You love playing games, I love making games.
I also use third party software for the leaderboards and I decided to update this. Maybe an update will already fix it. But I have to approach this carefully, as I don’t want to corrupt the leaderboards. Please don’t forget, egging usually costs less than a cup of coffee and even is free for now, no ads inside! So please be fair!
