Elder Guardians don't drop loot or leave Atlas when killed on character that didnt activate the map

Priority : P2 [Arguable as a Priority 1]
Severity : Major

Prerequisites
Must have two characters that can clear maps/Elder Guardians

Steps to Reproduce
1. Run Shaper afflicted maps until the Elder and his Guardians inhabit a map
2. Start a map inhabited by an elder guardian on one of the two characters
3. Progress to the Arena
4. Place a portal and log out
5. Log onto your other character
6. Go back into the map and kill the Elder Guardian
7. Observe

Results
No loot will drop from the Elder Guardian, and there will also be no change on the Atlas. The Guardian/Elder will still inhabit the same map(s).
This can result in major issues for players who have characters for fast map clear but struggle to kill bosses, leaving a necessity for another boss-killing character.

I don't know if this was intended to happen by GGG. If is intentional however, you can get around it by starting a map with your second character, switch to the fast clear char, then switch back to the boss-killer.

99.99% certain this is intentional.

It makes very little sense to be intentional.

You're able to finish a previously started map one a different character if it's not inhabited by Elder Guardians - so this should function the same.

Also a comment from Chris on a Reddit post that seems like the same issue points to this being not intended: https://www.reddit.com/r/pathofexile/comments/7k3aqc/i_may_have_just_discovered_a_huge_bug_with_the/

PrinceoftheDawn - you have a good solution. I will probably try that out so I can get rid of these damned Elder Guardians.
