Hello, devs,

Could someone point me where I go wrong in the following? My Differentials constantly fail to CI with the messages like this one:

exception 'PhabricatorWorkerPermanentFailureException' with message 'Lease "PHID-DRYL-sydepw7hjxlnim325sdu" never activated.' in /opt/phabricator/src/applications/harbormaster/step/HarbormasterLeaseWorkingCopyBuildStepImplementation.php:91
Stack trace:

I googled this and found a similar topic on Phab's bug tracker:
https://secure.phabricator.com/T10982
Not particularly helpful 'cause I don't really understand the internals of Phab.

This started to happen roughly when I moved my ghc hacking setup to a new hardware this summer. Maybe, that's connected. Also, what suspicious is that `arc diff` tries to push changes in master right away, so I have to pass --skip-staging. This wasn't the case before, I believe.
