Unknown block error

[Raspi-dude]

Hello, when I tried to run this on my world it seemed to run into unknown blocks. I have an original bed from an earlier version of the game when there was only the red bed, and when I updated my game to later versions that had colored beds it turned invisible but still works as a bed. I think this is causing issues because I get the issue down below. I think a good fix for this would be to just skip unknown blocks. Thanks for looking into this.

My error message is extremely misleading, sorry about that. What's happening is that there's data in the save files that is always 0 on any save file anyone has ever used with my converter. Because of that I couldn't figure out what it meant, and I assumed it was unused. For some reason, your world contains this unknown data, meaning there's something special about it that isn't in other worlds.

As a quick fix, you can open c:\temp\chunker-env\Lib\site-packages\mc3ds\convert.py in a text editor change raise ValueError to print:

raise ValueError(
    f"UNKNOWN UNKNOWN UNKNOWN 0x{unknown_block_data:02X}"
)

Also, do you mind sending the world files? Alternatively I can make my program extract just the information I need if you want. It's fine if you don't want to send it for whatever reason, but I might be able to make my program can properly handle this data if I can figure out what it means
