How to fix a wrong policy on a project?

I somehow ended up with a project in my organization that has a bunch of subprojects, but somehow also has its edit policy set to “obj.project.members”. From local testing, I think this policy should actually be set to “users” seeing how a super-project can’t actually have any members.

So my question is: How do I now change this policy so that we can actually make changes to this project?

I solved my own problem while browsing the server for access to the database. Inside the bin folder there was a utility called policy, calling bin/policy unblock PHID changed the policies of the object so that everybody could make changes again!
