I can’t even change my friends rank to a higher rank because of the current scaling on the group page, but I believe that issue only occurs with a few roles. This issue mainly depends on how many roles are in your group while attempting to update a players role in the group.
As you can see in the gif below, it only shows 2 roles although I have over 10. If you look closely you will also notice that under the “Jobs” button on the bottom of the screen you will see how bad the scaling really is at the moment as the page under the dropdown is being overlayed by the page below, which shouldn’t be hapening.
Here’s a gif of the person above the previous person, as you can see it shows most of the group roles, but for the first person I selected it didn’t show even half of the roles I have set into my group. But it still doesn’t show all of the roles I can rank someone to at this point it’s getting pretty annoying.
On the third person I selected which is three rows up from the bottom, it actually shows all of the roles I can rank to, which definitely shouldn’t be the case. It should show all of the roles I can rank to on all of the rows.
