If you're encountering missing sprites
**If you just updated to 6.6, do the reset cache steps mentioned in this #announcements message post.
**The game comes with all sprites preinstalled, up until the February 2025 Pack.
The remaining packs will be downloaded as you play, as long as you have "Download Data" turned on and your device is connected to wifi. You do not need to do anything for them.
Keep in mind, the auto download does not have infinite speed or capacity and will not trigger if you are not actively encountering new sprites (ex; battling, checking the Pokedex, etc.).
After downloading X amount of sprites per time unit Y, it will be paused for a bit. We cannot adjust this limit and there is nothing you can do as the player to skip it or make it go faster.
The first time you encounter a base Pokemon, it will select a random one of all sprites, if it is a new one that hasn't been downloaded yet, it will show as missing.
The same goes for fusions but with a little more nuance. To keep it simple, think of it the same.
Again, nothing wrong with your game. You just hit a download cap.
Note: Updating your game resets all your auto-downloaded sprites. do not attempt to "fix" this with updating. It will just make everything start from the beginning.
If you would like to manually import the latest sprite packs, they are located in #spritepack-releases and further instructions can be found HERE
