I've had this issue since i started playing on the server: when in a party and we have to roll for an item it only shows if I roll need/greed/pass and who wins the roll, but it doesn't show if the other players roll need/greed/pass or the roll results. I've been talking to other ppl in dungeons and some ppl have this issue.
The option to show the rolls in chat is marked in the options.
If anyone has been able to solve this problem and wants to share would appreciate it very much!
