Player sent back to the school on a multiplayer server

[mtvjr]

• Modpack Version: 1.2.0

• Issue: kc_tipin, a player on my multiplayer server, was sent back to the academy, his inventory being cleared.

KC had noticed his skin had returned to the default "Minecraft Alex" skin, and exited the game. He re logged into the game and when he joined the server, he was transported into the school and lost his current inventory.

When he exited the school, his quest progress was as it was before the incident and he was able to interact with his claimed chunks, but the items that were in his inventory were lost.

• Is it Repeatable?: No

This happened again, no clear sign on what caused it. Duplicated after restoring from backup.

Copy of world data with error occurring: https://www.mtvjr.dev/AcademyError.zip

Workaround:

1. Teleport the player outside the academy (such as with /home)
2. Have them drop / store their items. As the next step will erase their inventory.
3. Lastly open the quest book to allow world interaction.

Yes, same happened to me just today. I saved my world as I normally did, then logged again and I was teleported to school with all the inventory I had while mining. Then when I exited school my inventory was wiped. All this happened in a singleplayer world, and unfortunately I don't have any backup.

Same thing happened to me with singleplayer. Saved game and quit till the next day and loaded back into the school. tried to replicate it and it has happened on every world I try and after reinstalling mod pack.
