Hi, I'm facing an issue with fonts. For example, the raid names use the font I configured, but the debuff fonts use a fixed font called LunaUF.defaultFont

Maybe all SetFont calls should use the "Interface\\AddOns\\LunaUnitFrames\\media\\fonts\\"..LunaUF.db.profile.font..".ttf" font.

No, it is intended this way because you can set a crazy font for the text on the bars and still read debuff stacks.
