Sword/Shield boxes not working

LiveHex successfully connects, but it doesn't edit anything and the boxes are always empty even if they aren't.

Steps to reproduce the behavior:

1. Connect with LAN (i can't connect with internet and ldn-mitm doesn't work)
2. Put the IP in LiveHex
3. Press connect
4. The boxes show up empty even if they have something in it, and adding Pokémon won't show up in the game
