Hi Community !!
I need for something unusual, but an interesting challenge 
Situation:
1) There is a ticket ABC-123 which belongs to "Sprint 1" and "FixVersion 1"
2) The ticket has been done, and transitioned to "Done" status
So, some of the team members are changing the sprint value and FixVersion value for already DONE tickets.
How can I prevent it using Jira?
I know, that the best thing here is to follow up the process, explain and guide the team through the process, but it is really hard at this stage.
Could you advise on how can I prevent this kind of behavior using Jira stuff
Thanks,
Arthur
