I think just lazy to read. And then i wasnt sure how to add the new numbers. I was trying to put the new number outside the dice. And just clicking. Then i understood that it goes inside the dice but because i read lazy i did not understand that i need to add the new number to the place of number 1.
If im thinking how to clarify the first number change maybe there could be somekind of tutorial arrow to point that you need to replace it with 1.
