Modify LODS from compiled asset

I'm trying to use this asset https://sbox.game/fish/toilet, Its LOD 1 is an empty mesh causing the object to be hidden outside of the LOD 0 range. Is there a way to override this asset or extract / reuse the mesh in a new model to not have fucked lods?

I'm sure if you asked someone from smallfish, they would probably fix it :)
