I have a project which is corrupt.
With corrupt I mean eg., sprintreport doenst work (all completed issues are completed outside the sprint), Move to Done doesn't work (both the button as the auto-update when last subtask moves to done JIRA don't work).
Reason seems to be a custom field because when I create a new project with standard workflow etc all seems to work fine. When I move an issue from my current project to the new project Jira asks what to do with this custom field, a) adjust the new product b) discard this field. When I choose option b) all works fine, when I choose option a) it corrupts my new project.
