[1.20.1][Bug] C2ME wipes all items from Quark Storage Crates (mod conflict)

[mikkolukas]

Describe the bug
When latest version if C2ME for Minecraft 1.20.1 is installed, it removes all items from Quark Storage Crates when closing the server.

Runtime info:

• OS: Windows 11
• Minecraft version: 1.20.1

mods
On Client and server
Quark 1.20.1-4.0-460
Quark Oddities 1.20.1
Zeta 1.20.1-1.0-24

On server only
Concurrent Chunk Management Engine (Fabric) (aka C2ME) 0.2.0+alpha.11.15+1.20.1
Sinytra Connector 1.0.0-beta.46+1.20.1
Forgified Fabric API 0.92.2+1.11.10+1.20.1

To Reproduce

1. Launch a dedicated server as detailed above
2. Launch a new client instance as detailed above
3. Click Multiplayer
4. Join the server
5. Place a Storage Crate in the world
6. Put an item in the Storage Crate (I have used iron_axe in my testing)
7. Press [Escape] and click Disconnect
8. Restart the server
9. Join the server
10. Open the Storage Crate

What was expected: The item to be in the Storage Crate
What happened: The Storage Crate is empty

Workaround: Removing C2ME makes the Storage Crate work as expected (it doesn't bring the item back though).

Observation: Even when items are placed in a world while C2ME was not installed, then as soon as one stops the server with C2ME installed (even without making any changes to the world) the items disappear from the Storage Crate.

Crash reports / logs

• Client
  • mclo.gs/HSrFvXT
• Server
  • First run: mclo.gs/OW6UWSH
  • Second run: mclo.gs/bMQyFZZ

Checklist

• I am using the official version of the mod.
• I tried the latest development version (for 1.20.1) but the issue persists.
• I searched for similar open issues and could not find an existing bug report on this.

Additional context
As this issue only affects Quark Storage Crate and not other containers/interactive blocks in the mod, I have posted an issue for Quark also (link).

And yet, I suspect the issue stems from C2ME (or the connection through Sinytra 😬)

This might be more or less related to running on sinytra connector, as there's only partial support, and some forge APIs therefore can't be implemented.
For a proper port, use NeoForge 1.21.1 instead.

Yeah, I had a hunch that could come into play.

A LOT of mods are still on 1.20.1 though (including Quark, Create etc.)

I don't think this issue can be solved given there's virtually no way to have integration with forge APIs in a sinytra connector environment. Use 1.21.1 instead for fully supported neoforge port, or just ditch the idea of running C2ME over connector.
