[Bug] Crash with MrCrayfish's Furniture Refurbished

[WxAaRoNxW]

Describe the bug

When the server restarts abruptly, stops, or any sort of server closure without the client manually clicking disconnect, it would crash.

This only happens when a generator is in render. I'm not sure if all clients are affected if they're not in render range of the generator.

To Reproduce

1. Join a world (must not be singleplayer world)
2. Place a generator (doesn't have to be attached to anything)
3. Stop the server or close the server
4. Crash

Expected behavior

game goes to "disconnected menu" no crash
