[sliptype]

Description

• Instead of slicing the artist pick out of the response, set it to null and keep track of the null count to avoid messing up the offset

Dragons

Huh interesting for sure. Maybe we chat about it in person for all the context!

would also like to check that the lineup ends and doesn't try to load forever

Good call, there was some weird infinite load behavior at the end of the lineup. I ended up fixing the problem in a different way, it's not very elegant but I didn't want to use containsDeleted because we are no longer using it anywhere else and updated our endpoints to account for deleted items.

Essentially needed to keep track of "deleted" and "removed because of artist pick" separately, I did this by setting the artist pick item as null and keeping track of a nullCount. This fixes on both web and mobile
