Lcd clear() function working strangely

So I have a Mega 2560 and an LCD1602, I want to display the highscore of a game and change it after dying, my problem is that the clear function doesnt work properly when used in the gamescript but it does work properly when i use it in the tutorial hello world script. Also when I display the Highscore variable it shows 0 instead of the actual value.

Please post your last_will.ino (testament.ino [German]) - after having read General Guidance and How to use the Forum. :slight_smile:

What colour will it be dyed?
