@unknown, no. You indeed created this report but for some reasons you didn't touch (update) this ticket since you've created it (1+ year ago). That's why the moderater decided to change the reporter from you to someone else, so he/she can keep the report updated. Thank you for understanding.

Will not fix, the solution provided by OP will only solve the connecting pillar issue but creates a new continuity problem within the block itself, which is not something we want.
