Thank you very much for reporting this bug. As you stated, the overlay_raw_map did not use directory option (download the file irrespective of the option). I have now fixed the error and updated the version. Also, the overlay_raw_map now raises the error if the file does not exist in the directory. Please update the version by devtools::install_github("noriakis/ggkegg") if you are to use the new version.

Thanks again for reporting!
