Just a problem as of today, Pitbull, gotwood, aperature, all suddenly decided to reset ? I also run cartagrapher as the above poster. I update w/externals with WAU, and as of todays update this has happened. Has something changed that would only affect these mods ?
PitBull's default font and bar texture changed; other than that, none of your settings should have been reset. If they were, and since you say other addons were affected too, it's likely a problem with your computer.
I decided to disable cartographer to see if that was the cause of the problem and, well, it seems it was. Not sure what about cartographer was causing the issue though. Doing some more research and will post back with what I find.
Your copy of Cartographer had old libraries in it - if you update it you should be fine.
