Incompatible with Overgrown's Origins (NeoForge origins port) and Curios

[AiriAzalea]

Minecraft: 1.21.1
NeoForge: 21.1.248 via Sinytra Connector 2.0-beta.17
Switchy: 3.7.1

Incompatible mods
Overgrown's Apoli (with version 1.42.1)
Overgrown's Origins (with version 1.23.1)
Curios (with version 9.5.1)

Describe the bug
When switching via command or context menu, none of the relevant mod data swaps. Attempting to correct this via datapack causes the client to either disregard the change or crash due to not correctly working with NeoForgee's attachment system.

Steps to reproduce the behaviour

1. Create a fresh instance of 1.21.1 NeoForge
2. Install Connector with the relevant mods
3. Create a new world
4. Attempt switching profiles while the relevant mods have data attached.

Expected behaviour
Origin and curios swap with profile.
