When buying this gamepass from this game, the following dialog appears:
HALOLSO is not associated with the group in any way and I have no clue who this person is. What happens seems to be fairly obvious as the user and my group share the same UserID/GroupID and thus the dialog looks up the name from the wrong table:
User: https://www.roblox.com/users/1251857/profile
Group: https://www.roblox.com/My/Groups.aspx?gid=1251857
