Epic to done when linked issues are done

[barbora.severova]

Hi :) 

I'm still new in JIRA and have one question I can't resolved. 

Example:

I have project KSD and K3D. I create epic in KSD project and linked issues Story (KSD) and Bug (K3D). My goal is: when Story (KSD) and Bug (K3D) are done the epic in KSD will automatically be done too. 
I was trying to set it but know when I put Story (KSD) to done the Epic (KSD) is right away in done too. Despite the fact that the Bug (K3D) is still open. 

How can I set some "waiting" to all linked issues get closed no matter in what project they are in? 

I hope it's understandable. :D 

Thank you Barb

Hi Barbbora - Welcome to the Atlassian Community!

What are you using now to mark the Epic done when at least the story is done? Are you using an add-on for that? If so, which one?
