Coil Needs A 'Leaving Instance' Notification

So earlier today myself and some rl/FC friends spent quite a few hours at our first coil run.

We finally beat the boss at the end of turn one, everyone was quite excited as you can imagine, and we stated everyone have a break for an hour.
One person went AFK and didn't press 'Pass' on the loot roll, the rest of us went through the portal believing that it was like the portal in any other dungeon (not named 'Exit'), which takes you to Turn 2.
This is not the case.

Apparently when you go through this portal, there is no warning that you are leaving the instance, there is no warning that any loot unclaimed will be forfeited, there is nothing, yet you do in fact leave the instance and go to a sort of Turn 2 waiting room.

Needless to say, both items were given to this one AFK player.
He returned to have 7 other people extremely upset with him and he felt so bad.
He wants/wanted the items to go to the correct players.

I contacted the GM's in-game and explained what happened, to which they replied
"Greetings blah blah support desk

Unfortunately, we are unable to assist you with your request since we do not transfer items between players.

Thank you for your understanding and best wishes to you.

(great work SE, blanket ban thousands of players at once, remove gil, but can't rectify a silly mistake)

So basically I'm assuming SE support is going to be as useless as always and they will not be able to help me and my mates.
This does not mean that this should be fixed so that the same mistake is not made in the future by anyone else.

Firstly, the portal should be called 'Exit' like every other portal that leads out of an instance.
Secondly, there should be a notification alerting that "this portal is going to take you outside the instance and all unclaimed loot will be forfeited, do you accept?"

It seems like a common sense issue I know, but due to SE taking pretty much 3 months to make ToP/ToM changes, and being almost forced to run AK over 9000 times, I'm sure anyone would believe that a portal not named 'Exit' is not an exit...

This isn't a localization issue. Doesn't belong here.

However, your issue is somewhat valid, though I thought it was obvious that the end of the dungeon would take you out, and you should claim loot first.
