Filenames being cached despite changing from lower case to upper case

Pretty simple really. I have a file committed in a previous commit as filename.js which has since been renamed to something like FileName.js, however after SSHing into the box following a build error, circleci seems to be caching the filenames as the old one (e.g. the filename on circle is filename.js still).

I am sure this is probably an easy fix but as I am new to this CI tool, my guess is I need to flush the cache? Maybe this is a fundamental misunderstanding of how the linux/mac filesystems work with regards to case sensitivity.

ID10T error guys!

Git mv needed to rename files :smiley: . sorry
