One shot chests in multiplayer

One shot chests like the Warden’s, Cronley’s, Karroz’s, and even the hidden treasure in the croplands don’t appear in multiplayer.

I think it used to be that if the host had opened the chest in someone else’s game ahead of his story then the chest would not be in games he hosted even when his story mission is active.

Since 1.0.1.0 it seems they don’t show up at all in multi and they are there one time if you go back to single player.

Was this documented or intended? I suppose in multi players could get extra shots at one shots.
