Embarrassing! Haha. :P You’re absolutely right and I kinda wondered if keeping two different update tracks for a pack like this would come back to bite my butt. Today is that day.
Basically, it happened because I had a sprite-based update history (shared with Nine Realms) and the update history for the packs themselves. This, my friend, is a recipe for confusion and wildly inconsistent naming conventions.
Entirely my bad and sorry for any inconvenience. I’ll use incremental version numbers from here on out! If you notice anything wonky like this again, don’t hesitate to mention it.
