Describe the bug
Server Keeps having to skip an item called invisible item frame, an item that doesn't seem to show up at all in the files as a genuine item in the game.
it has been what seems to be the cause for crashes every do often and also clogs up the server logs A LOT Making troubleshooting other issues a pain.

To Reproduce
Run AOF6 Modpack server
Explore and monitor the server on CMD

Expected behavior
Not have to skip hundreds of entities called Invisible item frames? I am unsure what these even are???

Mod version
1.6.10

Screenshots

Unsure if that works but here is what each line says on repeat:

[03:21:47] [Worker-Main-7/WARN]: Skipping Entity with id spectrum:invisible_item_frame

One of the puzzle structures contains a saved entity spectrum:invisible_item_frame which is indeed not existent anymore, since it was renamed to spectrum:invisible_phantom_frame recently. This is fixed in the recent alphas. In the meantime you could for example override the structure nbt file via datapack with a version of the structure that does not contain that entity.

While this results in a bit of log spam since that entity fails to load when chunks are loaded (and rightfully so), I see no reason to believe that has anything to do with crashes?

since you know which puzzle structure, would you be able to link the puzzle structure and data path here so that folks can drop it in their kubejs/data/ folder to clear up the log spam. This should not be causing any crashes though.

This one:

Fixed in Spectrum's alpha builds.
