I created a mod where I set isNonstandard = "Past" for all Zygarde forms. However, I didn't manually set tier, doublesTier, and natDexTier to Illegal. When Zygarde-Complete attempts to derive the tiers from its base forms, it converts the array ["Zygarde", "Zygarde-10%"] into an ID. Consequently, it ends up trying to fetch the tier of an undefined element, causing a crash.
I'm unsure if this is the only part of the code affected, but it seems somewhat inefficient to have to set the tiers of all non-standard to Illegal just to avoid this bug (although this currently only impacts Zygarde-Complete and Necrozma-Ultra). Setting the tiers to Illegal avoids entering this part of the code.
