Red Chest's Loot

I finished Snarbolax yesterday and when I went to the prize area (after you kill snarbolax), I found a Crystal Bomb in one of those boxes, so I started to think: If someday, I went through somewhere with a party, like in Jelly Palace and when we finish Jelly and go to the prize area, we find a rare item, like 4* or whatever and press: Go Solo, the item will be there? If yes, everyone on the party could Go Solo only to get the item... I tested it with materials, and It worked, It dropped from a lichen and I went Solo, loaded the map and there it was... the material... Have anyone try with any Item? Bombs, Guns, Swords, Shields... Whatever... Anyone notice that could be a possibility to everyone get the item and not only one from the party?
Thanks, and reply please!

It could be nice if someone could test it, and first of all, tell your party members to don't rush on red chests, and be careful while getting stuff... And test it if possible ;)
Imagine if someday it drops an Divine Avenger or whatever... The person will be like shocked and will rush to get it, but there is a possibility to everyone have it... =)

Yes, please, I would be interested in this bit of info. Though if it happens, OOO will most likely patch it because "it would be an exploit that generates many crowns". And we couldn't blame them :/

I've tested this with materials before.
As soon as the item appears on screen, whether it has been picked up or not, it "belongs" to someone. [The game has already decided who it will go to.]
If it "belongs" to someone else and they go solo, the item will disappear from your instance and appear in the same spot in theirs.
If the item "belongs" to you, and the others go solo, it obviously just stays where it is, in your instance.
So no, no exploit.

I think treasurebox loot is different. It doesn't really BELONG to anyone once it drops. I believe that, once dropped, it is free pickings for any knight to pick up.

I think once you go solo, all items on the ground disappear, and regardless crowns are shared so you won't get more by splitting up.
I've been told that it works for weapons and armor too. But not personally confirmed.
