While attempting to update a member’s role to a higher one causes something really interesting: nothing happens.
Multiple admins have attempted to re-role the user “train_hello” from RankID 107 to 120 with no success. Roblox is returning code 200 (OK), with no 500. I am not sure why this is happening, so I am creating a bug report now.
GroupID: 35129505
Affected UserID: 2979646956
tl;dr: Attempting to re-role a member causes them to be reset to previous role.
From what I can tell, it appears there 2 entries of this user within the group, as they are showing RANKED in 2 ROLES.
Expected behavior
I except that the user retains selected role.
