hi,
regarding the loot, this is shown within the status ui - if you can see the status ui then you will always be able to see the loot unless you've disabled that option. if the status ui doesn't show (which includes the loot) then that is a known issue and is fixed in the next update. they need to re-enter the event two separate times after dying. so leave event, enter event, leave event, enter event. two times, not one time.
regarding the in-game map - this will not vary from person to person - if one player can see the event then every other player will see the same exact event with the same exact text. if an event doesn't show for any player on the map then it is a CopyPaste issue. make sure you are using the below CopyPaste plugin fix which contains many fixes for the current problems with that plugin.
