We have an issue with a single Epic not appearing on our Roadmap. The Epic is live and has the same settings as the other Epics (which are appearing). Some of the associated bugs and issues are showing as 'Issues without a parent' but when you open them they clearly have an Epic assigned.
Why is it it singling out this particular Epic and how do we get it to appear on our Roadmap?
For context, the Epic has various tasks, stories and bugs assigned to it. A release version (as do the tickets associated). Is in progress and in the current sprint. It has been assigned to an active assignee.
