Hello.
This is a bug that I've been noticing from a while, when you have somebody in an inbox discussion, and if they delete their character, it will not remove them from the participents list. I think this should be done, since there's no literal point of them in there as even if they recreate they are unable to retrieve the discussions anyway, since currently when i checked my participents list of a thread it said alphaxploder, godfather and alphaxploder , that meand that the said person deleted their char, and then recreated with the same name and i had to re add them since they weren't there, now since the first one did not get deleted, it caused two instances of the same person's name to be in the thread when one of them is real, other is gone.
