The blocks are missing, and the names are missing for some reason. The addon used to work fine in previous versions.

What I expected:
The addon would work fine like it did in previous versions

What I saw:
The blocks were misssing, and item names are gone, they used to be here in older versions of the game.

Notes:
I managed to reproduce this bug in a new world, so there was nothing wrong with the world i was using it in. I am not the creator, but I inspected the addon myself and couldn't find any issues with the code. I checked the content log and couldn't find anything. There were no errors or warnings in the packs (Missing dependencies, etc.)
