I just noticed that we were using #14318 patch on 3.4. It's really strange that this patch is available since 2.2 and not yet part of the core redmine yet!

The patch was rejected because the behavior may confuse users. See #14318#note-23 and #7412#note-13.

Without the patch, the redmine is almost unusable for us with the configuration mentioned in the description. We have applied the patch again and it worked on 4.1.1.

The watcher and whoever worked on that ticket should have the visibility on the ticket. AS I explained in the ticket, users are considered as staff and they don't have access to all the tickets of the projects. So the issue visibility on the role is set as "Issues created by or assigned to the user"

>>UserA assigns to the ticket to UserB (both of them can see the ticket). UserB adds comments and sets the assignee back to UserA and then clicks Submit, here the ticket is giving error "Issue is Invalid" and the ticket doesn't get updated.

To be honest, if this isn't a bug, redmine shouldn't be having the visibility option as "Issues created by or assigned to the user". Anyone using this visibility will face this issue and patch is the only solution to this.
