* test this

* gamer mode

* debug

* do it like this

* test

* test this

* stop it being weirdly relative

* more relative fixes

* try cat

* indentation

* update CI stuff to cache

* correct this

* yarn

* yarn consistency

* do we even need to do this? (no we don't)

* properly cache yarn deps in ci
