I think there should be like 1 000% where it drops a gold box and you would need (suggestion) 750 or 1000 score to get it. It should only be in non-pro battles because you will only have 15 minutes to do it.

I got the 250 kill tier on 2 separate occasions (celebrations) but I did not get my 3 golds. I used a calculator to check. Can you explain why I did not get my 3 golds for each one???
