I saw both 100% when in different zones and group members health dropped, AND I saw the red 0% when they were at full health. Back to the drawing board I guess on the %. I went so far as to delete my entire UI folder, re-download all files from here and from Sony, reinstall and still came up with that problem.
I also learned that the problem with the tradeskill UI (not being able to sort alphabetically) is indicative of the default UI and not something you did (makes sense since you didn't mod it) to the UI. I think I may have said I used a different piece than I actually do use. The piece I snagged and put in was Jaxel's skinned tradeskill mod, not miloquest's. Anyhow, Jaxel's gave me the ability to sort again and as a Sage that feature is absolutely necessary. Scrolling through 2k spells that Sony has mislabeled on levels is damn near impossible.
Hang in there Wulfster!! I'm sure it's just something minor. I wish I could code to help ya out.
