I think the Renown counter shown on the top left is not beeing updated as of V0.4. The value is correctly added as when I get to the shopt the renown counter there is correct, but the one shown in the top left at all times always displays 15.
You know what, I actually noticed this too, but only in the web version, so it's possible I overlooked it. Thanks a lot for pointing it out! I'll make sure to get it fixed in the next patch!
