[Client] Aatrox disappears in queue (all-for-one)

When you first enter champion ban/select in the all-for-one gamemode Aatrox is visible right in front of Ahri in the list of champions. As the opposing team selects their first ban, Aatrox will disappear. As your team selects a ban, he will reappear. This continues until all bans have been submitted, sometimes Aatrox will be available for selection, sometimes he is gone.

Entirely unrelated to being banned. He just doesn't exist on the list. This is also not 100% reliable and doesn't always happen but has been pretty consistent this evening.

(Boyfriend says it's likely an indexing error as Aatrox is first on the list)
