YN0018 with checked-in .yarn/cache

[eliw00d]

We check in our .yarn/cache folder but have nodeLinker: node-modules for now due to our usage of React Native. We recently onboarded some new engineers and right after cloning our repository and running yarn install they get YN0018 for every single file in the cache. Is this normal? We tried all manner of things to resolve this but ultimately had to add the .yarn/cache folder to our .gitignore because there was no way around it for these engineers.
