I have just upgraded a couple of sites from an earlier release of SS3 to the 3.0 stable build (CMS & Sapphire). Now, when I try to dev/build I am getting the following error (the site was working fine pre dev/build but is now showing this error everywhere):

PHP Fatal error:  Uncaught exception 'SS_DAG_CyclicException' with message 'DAG has cyclic requirements' in /Users/fraser/Documents/Work/HallPass/sapphire/core/DAG.php:73
Stack trace:

#5 {main}
  thrown in /Users/fraser/Documents/Work/HallPass/sapphire/core/DAG.php on line 73

Everything else works fine however, it's just when I do anything in /dev. I have made some changes and need to regenerate the manifest on these sites.

UPDATE: I have also tried a clean install of SS3 and am getting the same issue.

Any ideas?
