numbers do start to break later in the game, I've added 2 screenshots and copy+pasted the exported save for the second image just in case you need to take a look for yourself

small edit: in the first screenshot you can see 2 people with the 88 in their username that somebody brought up before, I know you said it is random but it really does show up super often. There is a bad group of people who like to put that number in their usernames online, you can google what the 88 means if you need to idk what itch.io tries to moderate in these comments. Might be something worth removing though just to be on the safe side
