issues using `cargo vendor`

Description

Projects depending on feather can not vendor their dependencies using cargo vendor

Reproduction Steps

git clone https://cyberchaos.dev/yuka/rnat
cd rnat
mkdir .cargo
cargo vendor > .cargo/config.toml
cargo build --all-features

What You Expected to Happen

The vendored versions of the feather crates should work standalone

What Actually Happened

libcraft-blocks-... attempts to load assets from outside its crate root, and fails to build
