I renamed it, and it loaded up the original UI but half of my bags doesnt show up. I guess it kept the same size from the other UI, but the original UI has a bigger bag size with bigger icons. Anyway to fix this?
yup. you'll have to move or delete your "server_character_eq2_uisettings.ini" files. these contain window placements. if the default UI windows are of different sizes than the custom UI windows you were using, the placements will be fubared. moving these temporarily will fix this until we get updated versions of our fav mods.
