Whisper Problems: Missing people can still be whispered

A while back, if I had to roughly estimate I would guess 4-5 months ago. Two people left my campaign but for whatever reason they still show up on the list of people I can whisper. It was fine at first, I figured it was due to some update and that it would go away with time but this has not been the case. Is there any way for me to fix this without making a whole new campaign?

There used to be a bug where people who quit left 'ghosts' behind. That bug has since been fixed but the 'ghosts' are still present. There are two methods for dealing with it: 1) PM me the campaign details link of your campaign (not the Join link) and the names of the 'ghosts' and I will forward it to the Devs. 2) Copy/Extend your campaign and uncheckmark the players box. You will then have to re-invite the players to the campaign and reconnect them to their assets (tokens and character sheets). If they have Macros (not character Abilities) they will be lost. I suggest method #1. :)

Indeed it is thank you very much.
