Old players allowed, new player not found

Pretty much what Metroknight said. If those two suggestions fail to help you, let us know.

Just to double check with you Robert, but are you the original creator for this campaign? If you are, I think something isn't working quite right in regards to booting the unwanted players.

Robert, could you send me a game invite and promote me to GM? That way I can see if the permissions are stuck on my end as well?

Robert. Your campaign is likely "gone", because it looks like you have two Roll20 accounts. Note that there's a "Robert L" and a "Robert Ling" posting here in this thread. I suspect your campaign is linked to the "Robert L" account. Edit: Confirmed that with the Devs. Going through Google+ sometimes creates a secondary Roll20 account using your G+ credentials when you join a Roll20 Hangout and your browser doesn't remember your login from our native website. It's suppose to help brand new players quickly get into their first Roll20 game without having to go through the trouble of being rerouted to our website to create an account.

Actually. Do you have anything you need saving on the Robert Ling account?

I logged into the campaign and noticed that Warduke and Mark S. are still available from the available players drop down list. I'll see if the Devs can figure out what's happening here.

I have disabled your "Robert Ling" account, and set your Robert L. account to be linked to your G+ account, so you shouldn't have any further issues in that regard. Regarding the players showing up, currently when you kick a player from a campaign, it just removes their permission to access the campaign itself, and removes their access to view the "outside the app" stuff (e.g. forums, etc.). However, their "Player" is still a part of your Campaign to keep it from breaking things. So they can't actually access the Campaign, and they can't get in the game anymore, but they do still show up in the Campaign drop-downs etc. At one point I think we had it removing them from the in-game dropdowns as well but it was causing campaigns to break. I will look into that further. But at any rate, that's what's going on.
