So BREAKING NEWS about the hotfix.
As by MARCIN's words here (in polish) http://forums.cdprojektred.com/thre...dotycząca-źle-zliczanego-doświadczenia/page25 the coming patch is going to fix the problem with missing exp
AND I am going to let you know the way. Behold please. Tremble. The brilliand and genius, thus simple decision:
The quests intended to grant you (wait for it) 0 exp will now grant (wait a bit more) 5 (omgwtfiddqd 5 exp!!!!!11) exp.
So it took them about a week and a whole lot of patch bundle to come up with it. And not to release it yet.
Ola bois.
Btw @Marcin Momot - y u hate the eng speaking community so badly u do not bother to write anything here, dear community manager sir?
On the same reply he also says that the patch will fix the bug that green quest are not giving XP. So calm your horses
