What did you do to cause this?
I moved a ticket from one project to another using the (relatively new) move feature. As part of the move, I assigned the ticket to myself.
What page were you on?
N/A. Email notification.
What PHP and MariaDB versions do you run?
Describe the defect:
The ticket number changed from whatever it was on the original project to the next-numbered ticket in the new project.
The notification email had a link to the old project using the new ticket number, which ends up pointing to a completely unrelated ticket.
The link sent as a notification during a move event should most likely be to the new project rather than the old project.
This should be fixed now.
