I was told that I have to show the fact that I am using the standard pack before the run, but I am submitting a run for a custom pack, and on the pets tab there is a picture of the kiwi bird, which means that I am on a custom pack, because otherwise the picture would be of something else, you can also see that I am in a custom pack because of the animals that I get in my shop, and the variation of animals could only be found in a custom pack.
