Where is it found in the files and could it be changed? ctrl k f1 just opens the help menu for me.
There's a way to delete the check entirely, but you'll need to decompile the game for that.
On the first message written on the thread you can find out how to do it yourself.
After you decompile the code you can go to the root of your game folder and click on game, then CLICKER (yes it's in all caps).
Finally you go to a file called "CLICKER.RPY", make sure you can edit what's inside of the file with an IDE or anything that can read Python code.
If you're in the file search for "def cl_has_cents" (CTRL + F), go down where it says "return res" edit it so it says "return True" also delete the line of code that's above it so it won't show the message anymore while playing.
Save the file and that should be it.
