After upgrading from CraftBukkit version git-Spigot-1a3504a-84f3da3 (MC: 1.13.2), players spawn in the default world rather than the last world they were in, while maintaining their previous coordinates. The updated world is set as `minecraft:overworld` rather than either real world name.

Prior to logging in, Multiverse-Inventories and the playerdata file confirm their prior world was not the main world.

The attached files are as follows:

1.13.2-WizardCM.dat - playerdata from before the upgrade (note the `SpawnWorld` and `DataVersion`)

1.20.2-WizardCM-initial.dat - playerdata from directly after the upgrade (note `SpawnWorld` is now gone, and `SpawnDimension` and `Dimension` appear instead)

1.20.2-WizardCM-corrected.dat - playerdata from manually teleporting to the correct world
