Bench Manager - Server Error IOError: [Errno 2] modules.txt

Hey guys,
Although last night everything worked perfectly, today in Bench Manager while trying to create a new Custom Doctype, I receive this server error out of the sudden:

IOError: [Errno 2] No such file or directory: u'/home/frappe/frappe-bench/env/local/lib/python2.7/site-packages/schedule/modules.txt'

Not sure what to do with it as everything was working perfectly until it did not anymore haha
