Ok, I'm quite confident that this means that you're not on the
wip/map-quartz branch.
Please check if 'git branch' returns a list of branches with
'wip/map-quartz' starred.
If not, please do 'git checkout wip/quartz-map', rebuild and test again.
(Fixing this issue with the mapping is exactly the purpose of the
wip/map-quartz branch).
Another way to check if you're on the right branch is to check if the
current state is 'git log'. It should show a list of commits and the
first one should be 6021ff13f5e7d8ab0b9692cf36ee055c45530134.
