I am assigned to a tasks that belong to an epic or that belong to a story which further belongs to an epic. Although I see the tasks in my board (the board always filters on me), I cannot see the epic in the roadmap. The assignee of the epic is not me, therefore that's why it's not showing up. On the other hand if I filter on my avatar in the Overview board, in the roadmap section, I can see that epic.
I think the avatar filter has a different JQL than just 'assignee in (userA, userB)' which is the filter I have applied to the board.
I would like also the epics of the tasks/stories I am assigned to, to show up in my board's roadmap, even if I am not the one assigned to the epic.
