I've asked the question before a couple months ago, but I tried to change my name since I've heard that "Into the Light" gave out a second name change, it's not working. I tried again now that "Final Shape" is out, but no go. The name is "SaintsThighsSaveLives", which I don't think violates the rules since I've seen similar names in-game. I use Firefox browser. Did changing my name back when name changes were originally given out keep me from being able to use the "Into the Light" name change? That's the only thing I can think of.
Hey there, if you can enter a new name, it means you do have a name change available.
If it is simply not saving, then it is hitting the filter, even if it seems like it shouldn't.
Names similar to that have been known to get reset to a Guardian default, names like those are only 'good' for as long as it takes them to be reported. So it could well be hitting the filter.
