Some AD&D games are shown as 13th age games. To fix this glitch, go into the game selection drop down menu. Select 13th age, then AD&D, then deselect 13th age. Should fix the issue. At least it worked once for me. :)
Are you saying that if someone selects 13th age for their "playing", it says AD&D or are you just indicating that there are people listing 13th Age as an AD&D game? If it is an actual misrepresenting when the proper system is selected, the dev's can look into it. If it is just a misunderstanding on what the system is then there is really nothing we can do about it.
