I have changed all my chars fonts to "Friz Quadrata TT", but every now and then it keeps resetting back to "Bazooka". Not really sure what causes this at all.

Closing.

mhmm, this might be some default setting returning, as Bazooka is coded to be set as default. I will check it out.

Is this still an issue?

I just noticed I had the "ClassicNumbers" addon enabled (but it is disabled in-game, it just shows up on Interface list) as I used it before I found this addon. Maybe it had to do something with that, will check.
