Playing a lvl 6 Sylvari Ranger in the lvl 1-15 Sylvari area, I completed 5 or 6 Renown Hearts and a couple of events. Then, when I tried to buy something with my karma (a recipe), I realized that I hadn’t any.
So, if you are a Dev, and read this, please fix this bug as soon as you can, because it’s a bit of a progression stopper, and quite annoying.
If you are a player, and read this, beware when doing the low level Sylvari Renown hearts and events, because you could end up without karma.
