Type of change

• [x] Bug fix

Description

Our use of cache_dir didn't actually resemble cache in the traditional sense. Cache would refer to semi-persistent storage that is reused between application runs. In our use, we overwrote it on every run, making it working memory. As such, it belongs in ram.

Ideally we can just concatenate right away.

This should fix #1178 and #1173, tho concatenation would be a more direct fix.
