Players authing on a TC then authing a friend break the logic on this plugin. Anyone else can confirm for me please??

Also the same problem here. Authorize friend kills the first owner of the TC and it is no longer possible to authenticate yourself again.

I thought it was a carbon issue since I moved to carbon at the same time
Changed in function OnCupboardAuthorize

comment this:

//privilege.authorizedPlayers.RemoveWhere(x => x.userid == player.userID);

and change "<" to "<="

if (privilege.authorizedPlayers.Count <= limit.MaxAuthorized)

I forgot that I was running carbon. This fixed the problem so you can register again. But I believe that the maximum number is not taken into account under carbon. I set up a max. of eight and could register more as eight without getting a warning. As far as I know, a carbon developer is already looking at it. Maybe something is wrong in carbon.
