Reproduce the report with `zeus.py -l dorks.txt --proxy-file proxies.txt`, then inspect `lib/core/settings.py` around `get_proxy_type` and `proxy_string_to_dict`, followed by `var/search/selenium_search.py` around `parse_search_results`. Done means proxy-file input no longer raises the reported `InvalidProxyType` exception during search.
