In the last week or so I noticed that nameplate bars no longer can be adjusted in width. I had shortened the length of the nameplate bars using a feature at the bottom of the page on neat plates addon but it no longer works. When it first happened it still showed me the reduced size I wanted with some lines around it but then the bar just extended out on both sides to the length of the regular bar anyway.

It should have been fixed as of version 6.23.1

Make sure you've restarted the game client, and check that the version is correct.

It seems that I had accidentally removed the Healthbar from the list of width adjustments that this setting affects when I was added some new ones in the last major update. Which is why you only saw the healthbar border changing width, but not the actual health.

It should be fixed in the latest release.
